Hogwarts Castle is a large, seven-story high building supported by magic, with a hundred and forty two staircases throughout its many towers and turrets and very deep dungeons. The castle was built in the late Early Middle Ages (c. 993) by a wizard architect and the four most celebrated wizards of the age: Godric Gryffindor, Helga Hufflepuff, Rowena Ravenclaw and Salazar Slytherin. The castle is the main building of Hogwarts School of Witchcraft and Wizardry, regarded as the finest wizarding school in the world.

Hogwarts is built in a valley area — surrounding mountains are part of the landscape — with the fairly large Great Lake to the south of the main building. The huge main oak front doors leading into the Entrance Hall face the west, and open up to sloping lawns. The deep Forbidden Forest extends around to the west of the castle. There are also exterior greenhouses and vegetable patches on the school grounds.

Hogwarts is located in the Scottish Highlands, near the all-wizard village of Hogsmeade and "not far" from Dufftown, in Banffshire, and Achintee, in Lochaber.

It was the setting of the final battle of the Second Wizarding War, the Battle of Hogwarts, which resulted in the deaths of several witches and wizards who fought in defence of the castle, including Remus Lupin, Nymphadora Tonks, Fred Weasley, Colin Creevey, Lavender Brown, and Severus Snape. The castle was badly damaged in the battle, but ultimately the Order of the Phoenix won when Harry Potter defeated his nemesis, Lord Voldemort, in the Great Hall.

Due to its extremely advanced age and the sheer amount of magic present in or around it, the castle is implied to have developed some form of sentience or awareness, such as when it sealed the Headmaster's Tower against Dolores Umbridge in 1996, and the various trick steps and false doors.

Magic

Hogwarts in 1998

The castle is supported by magic (unable to be maintained or constructed by any other means), a good example being the moving staircases, a feature contributed by one of the four Hogwarts founders, Rowena Ravenclaw.

Hogwarts is also protected by numerous ancient spells, such as the Anti-Disapparition Jinx; this can, however, be overridden by the Headmaster (and Dumbledore's phoenix, Fawkes) when necessary. It is also unplottable and has been bewitched so that, if Muggles approach the castle, all they will see is a mouldering ruin with a sign warning them to keep out and that it is unsafe. The protective magic over Hogwarts is not only strong enough to apparently resist the dispelling effects of the Taboo but also to repel even talented dark wizards.

Rubeus Hagrid claimed that Hogwarts is the safest place in there is, even more so than Gringotts Wizarding Bank, a reason why the Philosopher's Stone was sent to the castle for protection. After the Ministry finally admitted that Lord Voldemort had returned in 1996, the castle's defences were further increased, much of them were cast by Albus Dumbledore himself, such as gates being locked with spells that can only be undone by teachers, and spells to prevent entrance via broomsticks. All of the secret passageways that were previously allegedly unknown were given more protection. Additionally, with members of the Order of the Phoenix and Aurors placed as guards, and Caretaker Argus Filch checking all incoming and outgoing students for dangerous materials, intrusion seemed completely impossible. However, Draco Malfoy utilised a pair of Vanishing Cabinets as a passageway, which none of the castle's defences could negate, to allow Death Eaters into the castle. This devastatingly horrified the wizarding community, as they realise that Hogwarts, the most powerful and reputably safest magical stronghold in the entire wizarding world, has been breached, much less by a student from the inside, meaning there is no longer anywhere safe from Voldemort and his Death Eaters.

As a result of all the magic that occurs on premises (both from learning students, magical artefacts therein and the enchantments cast over the building itself) a magical atmosphere pervades the entire structure, causing any technology that is not adapted to run off of it to fail. This is presumably why candles and lanterns are still in use. Mechanical things like watches seem to do all right, as Colin Creevey's (traditional, Muggle) camera seems to have worked until it was destroyed by the Basilisk's eyes. (Colin mentions that another student told him that he could develop the pictures in a potion so that they moved. One of his pictures shows Harry trying to escape a picture of him and Gilderoy Lockhart.)

Below the Ground Floor

Chamber of Secrets

"He was standing at the end of a long, dimly lit chamber. Towering stone pillars entwined with more serpents, rose to a ceiling lost in darkness, casting long, black shadows through the odd, greenish gloom that filled the place."

— Harry exploring the Chamber

The Chamber of Secrets

The Chamber of Secrets was allegedly created deep under the dungeons of Hogwarts Castle during the Medieval times by Salazar Slytherin, who disagreed with the other Hogwarts Founders on the merits of blood purity. The Chamber of Secrets was home to an ancient Basilisk, which was intended to be used to purge the school of Muggle - born students. The entrance can be found in Moaning Myrtle's bathroom on the second floor. In order to gain entrance one must say "open" in Parseltongue and a sink will open into a slide. While falling down the large, dark pipe, one can see hundreds of other pipes leading off. At the end of the pipe, one is launched into a damp, stone chamber. This room is stated to be "miles beneath the school" and under the Lake. This is where Tom Marvolo Riddle used his ability to speak parseltongue and attack Harry Potter.

Dungeons

The dungeons of Hogwarts Castle are located under the school, and it is colder there than in the main castle.

Dungeon cupboard

This cupboard is a small room off the Dungeon Corridor, just before the dungeon hall.

Deathday Party Hall

This was one of the roomier dungeons at Hogwarts Castle. The room is accessible via the Dungeon Staircase. On 31 October, 1992, this dungeon was where Sir Nicholas de Mimsy-Porpington's five-hundredth Deathday Party was held.

Potions Classroom

The Potions Classroom is where Potions classes are taught. The classroom used to be squared-sized, very large, with large tables and windows. From 1995-1996, the classroom was an oval shape and relatively smaller, with small work tables. In 1996, the classroom was extended, adding space for more work tables.

Potions basement

There is a storage basement under the Potions classroom at Hogwarts Castle. It is accessible via a trapdoor and it is used to store cauldrons, ingredients and phials.

Head of Slytherin's Office

This office was used by Severus Snape during his long tenure as Potions Master at Hogwarts. It was a gloomy and dimly-lit room found in the school Dungeons. The shadowy walls were lined with shelves of large glass jars filled with slimy, revolting things, such as bits of animals and plants, floating in potions of varying colours. The office had a fireplace. In a corner, there was a cupboard containing Snape's private stock of potion ingredients. The office is sealed with a spell only wizards can break.

Slytherin Common Room

The Slytherin Dungeon is located behind a wall in the dungeons of Hogwarts. A Password spoken to the wall is required to enter it; whereupon a passage is revealed leading to the Common room—a low-ceilinged, dungeon-like room with greenish lamps and chairs. This dungeon extends partway under the lake. Off of this room also includes the Slytherin Boys Dormitory.

Philosopher's Stone chambers

These chambers were a series of rooms underneath Hogwarts School of Witchcraft and Wizardry that served as the defences surrounding the Philosopher's Stone during the 1991–1992 school year. There were seven chambers in total that contained an obstacle or task that guarded the stone against being stolen.

1. Fluffy (Stationed in the Third Floor Right Corridor guarding the trap door entrance to the chambers below)
2. Devil's Snare
3. Winged Keys
4. Human Chess Game
5. Troll
6. Logic riddle
7. Mirror of Erised

Basement

Hufflepuff Common Room

"It is a very cosy and welcoming place, as dissimilar as possible from Snape’s dungeon. Lots of yellow hangings, and fat armchairs, and little underground tunnels leading to the dormitories, all of which have perfectly round doors, like barrel tops"

— Description

The Hufflepuff Basement is the common room for Hufflepuff students at Hogwarts. The entrance to the Hufflepuff Basement is hidden behind a stack of barrels. It can be entered by tapping a certain rhythm on the barrels. It is located near the kitchens. The cellar is decorated with yellow hangings and filled with fat armchairs. Underground tunnels lead off to the students' dormitories and all the doors are perfectly circular, like barrel tops. This is the only common room Harry Potter does not enter at some point during his years at Hogwarts.

Kitchens

The Hogwarts kitchen is located directly under the Great Hall, down the same staircase that leads to the Hufflepuff Common Room. It contains tables identical to those in the Great Hall and are directly below them; food must simply be placed on the tables in the kitchens, and it magically appears in the Great Hall. The kitchens are staffed by over 100 house-elves including Dobby, Winky, and Kreacher (after Harry Potter inherited him and ordered him there in 1996). To gain access to the kitchens, one must tickle the pear on a fruit portrait, which then turns into a door knob.

Boathouse

The Boathouse is an underground harbour at Hogwarts where the boats are stored and docked after bringing the first years to the castle every 1 September. Up until 1995 a portrait of Percival Pratt, hung on the walls, concealing a short-cut to the Grand Staircase. After Pratt's portrait was removed, there were only three entrances to this building: the path outside the Paved Courtyard, the stairs down from the Viaduct Courtyard, and the Great Lake.

Ground Floor

Entrance Hall

The Hogwarts Entrance Hall is located on the ground floor of Hogwarts School of Witchcraft and Wizardry, with a wide marble staircase opposite the oak doors. Double doors to the right lead into the Great Hall. The basement, the kitchens, the dungeons, and the Grand Staircase can also be accessed via the Entrance Hall. There is also an annexe off the hall where Professor McGonagall speaks to the first years before the Sorting ceremony at the beginning of each school year.

Chamber of Reception

The Chamber of Reception is a little building before the Entrance Hall where Professor Minerva McGonagall makes the first year students wait before the Sorting ceremony and the Welcoming Feast.

Viaduct Courtyard

The Viaduct Courtyard is located off the Entrance Hall. Most students witnessed the departure of Fred and George Weasley here in the spring of 1996. This courtyard replaced the Entrance Hall antechamber beyond 1994. Part of the Battle of Hogwarts was fought here on 2 May, 1998 and in response the courtyard sustained damage along with most other parts of the school.It can be assumed that after the battle the courtyard was repaired.

Great Hall

The Great Hall in Hogwarts is the main gathering area in the school. Students eat their meals, receive daily owl posts, and have certain special events. The Great Hall is a large hall that can easily hold all of the school's students, staff and guests. It has tall walls that reach up to the ceiling, which is enchanted to look like the sky above. It was the scene of Harry Potter and Lord Voldemort's final showdown, which was the Dark Lord's ultimate defeat. This was because the Elder Wand refuse to kill its true master, so Harry was not killed. Since Voldemort was now a mortal man, the curse rebounded on him, killing Tom Marvolo Riddle once and for all.

Staffroom

A long, panelled room with mismatched, dark wooden chairs. There is a wardrobe inside it which was once home to a Boggart. The entrance to this room is guarded by two talking stone gargoyles.

Caretaker's Office

The caretaker's office is the room where Argus Filch lived in Hogwarts Castle. It is connected to the Entrance Hall, on the Ground Floor of Hogwarts Castle. It is a small, simple, windowless room with a single oil lamp in the ceiling. It smells vaguely of fried fish.

Transfiguration Courtyard

This is one of the cloisters in the inner part of Hogwarts Castle. This courtyard has grass in the open area, in which a big tree has grown over the centuries. There is one massive iron Armillary Sphere that stands in the centre of the courtyard.

Transfiguration department

This is a wing at Hogwarts Castle containing the rooms dedicated to the teaching of Transfiguration. The Transfiguration department is presumably located around the Middle Courtyard area, including such rooms as Classroom 1B.

Transfiguration Classroom

This classroom is where Transfiguration class is taught. The classroom is located on the ground floor around the Middle Courtyard. The classroom itself is big, surrounded by high windows, has four rows of three desks, and still has enough room for several cages and bookshelves, two chalkboards, and a desk.

Classroom Eleven

Classroom Eleven is on the ground floor of Hogwarts Castle. It was used by the Centaur Firenze, who taught the subject of Divination. Albus Dumbledore changed the room to look like the Forbidden Forest, Firenze's home.

Viaduct Entrance

A big chamber which connects the Viaduct to the first floor by a staircase that leads to the Tapestry Corridor. There is also an archway that leads down the Potions staircase to the Dungeon Corridor.

The Quad

This courtyard is located on the Hogwarts Castle exterior area. It is connected to the Viaduct and the boathouse.

Viaduct

This viaduct is constructed of stone, and extends all the way down to the lake. It is connected to the Viaduct Courtyard at one end and is connected to the left long viaduct tower and the right long viaduct tower.

The multiple staircases in the Grand Staircase lead from platform to platform and go as high as the seventh floor where they come to an end.

First Floor

Defence Against the Dark Arts Classroom

This classroom is where Defence Against the Dark Arts class is taught. An iron chandelier hung from the ceiling, as well as a Dragon's skeleton. On one end of the classroom stands a projector that is activated by magic. Several desks and tables can be found in the classroom as well as some sets of large windows. The classroom decoration had several changes over the years, spanning from lots of pictures of Gilderoy Lockhart to tons of skeletons and Shrunken Heads.

History of Magic Classroom

This classroom is where History of Magic classes are taught at Hogwarts School of Witchcraft and Wizardry. The subject is taught by Professor Cuthbert Binns, a ghost, who is widely regarded by almost all Hogwarts students as the most monotonous and boring teacher in existence.

Muggle Studies Classroom

This classroom is where Muggle Studies classes are taught at Hogwarts School of Witchcraft and Wizardry.

Hospital Wing

The Hospital wing was run by Poppy Pomfrey. Students who suffer mishaps during the school year are sent or brought to the hospital wing for treatment. The hospital wing is well equipped to deal with all manner of magical and mundane injuries, from broken limbs to regrowing lost bones. Only in the most severe cases are students sent to St Mungo's Hospital for Magical Maladies and Injuries for further treatment, such as when Katie Bell touched a cursed Opal necklace in 1996.

Matron's Office

This office is a large room adjacent to the Hospital Wing at Hogwarts Castle owned by Poppy Pomfrey, the matron. It contains a bookcase, a desk, two closets, two beds for patients, and another bed closed off from the room by a curtain.

This corridor located on the first floor of Hogwarts Castle. It connects the Viaduct Entrance to the main first floor. Its walls are covered in tapestries and, hung over the tapestries, portraits of wizards.

Storeroom

This storeroom is located in the Tapestry Corridor, this was where Severus Snape stored his private supply of potions and potion ingredients. It was one of two known potions' store rooms in the castle; this being his private store; the other being the student store cupboard. The students cupboard is located in the dungeons. Items stored in Snape's store room included Veritaserum and ingredients for Polyjuice Potion.

Girls' Lavatory

Located on the first floor, this was where a Mountain Troll attacked Hermione Granger on 31 October, 1991.

Girl's Lavatory - Out of Order (Moaning Myrtle's Bathroom)

This girls' lavatory (also known as Moaning Myrtle's Bathroom) is situated on the first floor of Hogwarts Castle. It has been out of order ever since a student named Myrtle was killed there by Salazar Slytherin's Basilisk on the orders of Tom Riddle, the Heir of Slytherin. Myrtle has haunted the bathroom ever since, leading it to be a place most students do not want to enter. This bathroom holds the entrance to the Chamber of Secrets.

The Quad battlements

There were battlements all around the top of The Quad at Hogwarts Castle.

These battlements were used by the Hogwarts defence during the Battle of Hogwarts. They were heavily damaged during the course of the battle, with parts of the floor falling in, revealing the corridors below.

Clock Tower Entrance

This is one of the three main entrances of Hogwarts Castle. It consists of a large open space at the base of the Clock Tower with two stairwells going up towards the upper levels of the tower. Opposite the main entry there is a large window. A portrait of Damara Dodderidge was hung here and, in 1995, so was a portrait of Termeritus Shanks. The massive pendulum of the Clock swings over this entrance. The entrance can be sealed with a portcullis (which can be lowered and raised with the aid of a lever) and the massive double doors can be locked with numerous bolts.

Library

The Library is located on the third and fourth floors of Hogwarts School of Witchcraft and Wizardry and contains tens of thousands of books on thousands of shelves. Overseen by Madam Irma Pince, the library is where students can go to peruse or borrow books to supplement their studies (or for personal enjoyment). The library closes at 8 pm.

One-Eyed Witch Passage

The One-Eyed Witch Passage is a secret tunnel that leads from Hogwarts to the cellar of Honeydukes Sweetshop in Hogsmeade. Harry Potter first learned of it from Fred and George Weasley when they gave him the Marauder's Map in 1993.

Trophy Room

The Trophy Room is where awards, trophies, cups, plates, shields, statues, and medals are kept in crystal glass displays. This room also contains a list of Head Boys and Head Girls. Prominently displayed are Hogwarts Awards for Services to the School, with known recipients being Tom Marvolo Riddle, Harry Potter and Ron Weasley. Probably, in 1995, the Triwizard Cup was placed here as well. The Trophy Room is connected to an Armour Gallery.

Third Floor Corridor

The Third Floor Corridor on the right side of the Castle was out of bounds during the 1991–1992 school year because it was the access point to the Chambers where the Philosopher's Stone was being hidden.

This was where Sirius Black was held captive, awaiting the Dementor's Kiss in 1993. He was rescued by Harry Potter and Hermione Granger, and escaped on Buckbeak the Hippogriff.

Room of Requirement

The Room of Requirement is a secret room in Hogwarts that only appears when a person is in great need of it. The room then transforms itself into whatever the witch or wizard needs it to be at that moment. It is believed that the room is Unplottable, as it does not appear on the Marauder's Map, nor do its occupants, although this could simply be because James Potter, Remus Lupin, Sirius Black, and Peter Pettigrew who were the Marauders respectively, never found the room.

Hall of Hexes

The Hall of Hexes is a hall on the seventh-floor of Hogwarts Castle, close to the Room of Requirement.

Arithmancy classroom

This corridor contains the portrait of the Fat Lady that serves as the entrance to Gryffindor Tower. The corridor is at least one turn away from the Grand Staircase. In the 1993-1994 school year, security trolls were stationed here to protect the Fat Lady following the attack on her by Sirius Black.

North Wing

This wing has hundreds of bookshelves lined along the walls and various tables and furniture placed around the room. It serves the Castle as a reading room and study hall. There are two entrances; one in the seventh floor corridor and the other by the Fat Lady's portrait.

Disused Bathroom

This bathroom is accessible through a portrait in the reading room, as well as a door on the other side of the castle. It was unused prior to 1991, by which time Fred and George Weasley had taken up residence there and set up their own shop for Gryffindor students. In 1993, the twins abandoned the bathroom and set up their shop in a different bathroom on the sixth floor in the Glanmore Peakes' Corridor.

Divination Classroom

This is where Divination classes are taught at Hogwarts. It is located in the North Tower. It is accessible through a circular trapdoor and is described as looking like a cross between somebody's attic and an old-fashioned teashop. The Divination Staircase leads to this classroom.

Towers

Astronomy Tower

The Astronomy Tower is the tallest tower at Hogwarts Castle surrounded by a parapet and turret. It is where students study the stars and planets through their telescopes in Astronomy lessons with Professor Aurora Sinistra. This is usually done at midnight where the stars are best seen. The tower is usually out-of-bounds except for classes. All the way down from the boathouse you can see the huge window of the Astronomy Tower. Located within this tower is the Astronomy Corridor, Astronomy reading room, Astronomy classroom, Astronomy stairwell, Astronomy department and the Astronomy Room. In 1997, Hogwarts' headmaster, Albus Dumbledore was killed here on this tower by his eventual successor, Severus Snape. However, it was planned between Dumbledore and Snape to spare Draco Malfoy being a murderer and spare the headmaster from a slow painful death. This was because Dumbledore's hand was poisoned by a dangerous curse created by Tom Marvolo Riddle, to protect his Horcrux (Marvolo Gaunt's ring).

Bell Towers

The Bell Towers are two towers that rise over the main entrance to the Herbology Greenhouses. Between the two towers are a set of double wooden doors which lead along the Ground Floor Corridor. Inside the left Bell Tower is Filch's Office.

Clock Tower

The Clock Tower does not begin at the Ground Floor level. Because it is placed on top of a hill, the Tower begins at the Third Floor level. When you enter the Tower, there is a huge space, like an Entrance Hall with flights of wooden stairs at the right and left side. The first landing is at the Fourth Floor level. It is at this landing that are the clock's gears and face. This same corridor connects the Tower to the remaining castle. If you go up another flight of wooden stairs, you will get to another landing, this time at the Fifth Floor level. It is in this landing that are the clock's bells; some massive gold and copper bells. There is another corridor at this landing; like the other, it links the Tower to the main castle.

Dark Tower

The Dark Tower is a small but high tower near the Transfiguration Courtyard at Hogwarts Castle. This tower seems to be used as a prison. It has several prison cells, with the topmost being at the roof. The cells are not, however, charmed or otherwise protected against breaking-in from the outside. It has seven floors.

Defence Against the Dark Arts Tower

The Defence Against the Dark Arts Tower overlooks the Suspension Bridge. The tower has a "semi-circular" shape and is where DADA lessons are held and where the DADA professor's office is. Minerva McGonagall's office is located on the first floor of this tower. The Defence Against the Dark Arts staircase runs through the centre of this tower.

Grand Staircase Tower

This tower is probably the most prominent and recognisable feature of Hogwarts Castle. The tower is a circular shape and has a cone shaped roof. The Grand Staircase is located here, and at the top of this tower, are three smaller towers which make up the Headmaster's tower and serve as the Headmaster's office and residence.

Gryffindor Tower

Gryffindor Tower is located behind the portrait of the Fat Lady on the Seventh Floor of Hogwarts Castle. A Password is required to enter it, which is spoken to the portrait. A circular hole is behind the painting, leading to the Common room, which is a circular room where Gryffindor students can relax after a long day of studying. The Common room is full of squashy armchairs, tables, and a bulletin board where school notices, ads, lost posters, etc. can be posted. A window looks out onto the grounds of the school, and a large fireplace dominates one wall.

The Gryffindor dormitories are also located in the Tower, with two doors leading off from the Common room that open to spiral staircases. One of them leads to the girls dormitory, the other to the boys. The stairs to the girls dormitories are enchanted to become a slide if any boy attempts to climb them, but not vice-versa, since it was deemed that girls were more trustworthy than boys.

Headmaster's Tower

The Headmaster's office is located within this tower. To gain entrance, a password must be given to a stone gargoyle, which will move aside at the correct password to reveal a spiral staircase with moving steps. The office is a circular room with windows, decorated with portraits of previous Headmasters including Dilys Derwent and Phineas Nigellus Black. Many magical instruments are kept here, such as the Sorting Hat and the Pensieve.

Hospital Tower

The Hospital Tower has a semi-ovular shape. It is located on one side of The Quad and is at the end of the hospital corridor which connects the Clock Tower to the rest of the castle. On the first floor of the tower is the Hospital Wing and school matron's office. There is also a staircase that leads to the fourth-floor corridor and, by extension, to the Grand Staircase.

North Tower

The North Tower is one of the many towers in the castle. The tower is the location for Divination classes and the Divination teacher's office. The entrance consists of a ladder leading through a trap door.

Ravenclaw Tower

The Ravenclaw Tower is located on the west side of Hogwarts, the staircase leading up to the common room is presumably located on the fifth floor, and is the location of the Ravenclaw common room and dormitories. The entrance to the room is at the top of a spiral staircase, and is a door without doorknob or keyhole but a bronze knocker in the shape of an eagle. In order to enter the room, you must answer a question asked by the eagle knocker; if you answer wrong, you must wait for someone who gets it right.

Stone Bridge Tower

This is one of the four towers surrounding The Quad. It overlooks the Stone Bridge. The first floor landing of the tower goes over here connecting the First-floor corridor to the Stone Bridge.

West Tower

The Owlery is located on the top of this tower. During the winter months, the tower is very cold, to the point that one has to be careful with ice on the higher landings. A tightly spiralling staircase leads from the bottom of the tower on the seventh floor up to a door leading out onto the battlements.

The Grounds

Gamekeeper's Hut

The gamekeeper's hut is located on the edge of the Forbidden Forest. Rubeus Hagrid, the gamekeeper during Harry Potter's time at Hogwarts, lived here for many years.

The Forbidden Forest

Also known as Dark Forest or Black Forest, the forest borders the edges of the Hogwarts School of Witchcraft and Wizardry grounds. As its name suggests, it is strictly off limits to students - except in the case of detention, or Care of Magical Creatures lessons that occasionally take place there. Of course, with the various dangerous creatures, such as centaurs, Thestrals, unicorns, Hippogriffs and Acromantula living in the Forest, few students would probably even want to venture into it.

Greenhouses and Gardens

There are at least three greenhouses in which Herbology classes are held, under Professor Sprout's supervision. Greenhouse Three is restricted to students as it houses dangerous plants such as Venomous Tentaculas, Mandrakes, and others.

The Lake

File:1000px-Lke.jpg

The Great Lake is a large body of water located to the south of the castle. It is about half a mile in diameter and the Hogwarts plumbing network drains into it. It is home to a giant squid and a colony of Merpeople. The lake was also used as the site of the Second Task of the Triwizard Tournament.

Quidditch Pitch

The school has its own Quidditch pitch where each house's Quidditch teams practise and play games against each other. Each year will see a total of six inter-house matches, along with numerous training sessions by each house team.

Quidditch Gate

The Quidditch Gate is the entrance to the Quidditch Pitch. It is flanked by two stone structures which resemble two of the spectator towers surrounding the pitch. Inside the gate, several trophies and shields are housed. Through the gates leads to a steep winding downhill decent from the vicinity of the Wooden Bridge.

Entrance Gates

The Entrance Gates to Hogwarts are located a short distance from Hogsmeade Station. The gates would be opened on the first day of term and carriages pulled by Thestrals would take students up to the castle. The Entrance Gates are made of magnificent wrought iron and are flanked by two columns topped with statues of winged boars. Just a few yards from the gates is a small guardhouse with a tall chimney.

Clock Tower Courtyard

The Clock Tower Courtyard is a cloister on the base of the Clock Tower at Hogwarts School of Witchcraft and Wizardry. This cloister seems to be one of the older parts of the castle and the ceiling and walls are dilapidated. It also leads to the Wooden Bridge.

Wooden Bridge

The Wooden Bridge is a feature of Hogwarts Castle. The bridge appears derelict, and is constructed of wood beams which extend to the floor of the ravine it lays across. The roof of the Wooden Bridge is sagging and appears thatched and tarred. The bridge blends in with the natural environment surrounding it.

The Wooden Bridge begins at one end of the Clock Tower Courtyard, at the base of the Clock Tower. At the end of the Wooden Bridge there is a small stone gazebo with benches. Outside of it is the Sundial Garden. Given its unstable look it is possibly held up by magic.

Training Grounds

This is where Flying classes are taught to first years at Hogwarts School of Witchcraft and Wizardry by Madam Hooch. The grounds are flat, short-cut grassy areas and are located near the Herbology greenhouses. It is overlooked by the Training Grounds Tower.

White Tomb

The White Tomb is the only grave at Hogwarts School of Witchcraft and Wizardry. Located on the shores of the Lake, it is the final resting place of Albus Dumbledore, who willingly gave his life in the service of the Order of the Phoenix fighting Lord Voldemort's Death Eaters in the course of the Second Wizarding War.

Other locations on the grounds

• Entrance Footpath
• Gargoyle Gate
• Road to Hogwarts
• Rubeus Hagrid's pumpkin patch
• Sundial Garden
• Secret room near the Training Grounds
• Rubeus Hagrid's garden
• Waterfall

Unknown locations

Book of Monster's Repair Workshop

The Book of Monster's Repair Workshop is one of the rooms at Hogwarts Castle that is seen on the Marauder's Map. It is, presumably, the place where damaged copies of The Monster Book of Monsters are repaired.

Cauldron cupboard

The Cauldron cupboard is one of the rooms seen on the Marauder's Map. It is possibly a store room where cauldrons are kept. It is possible that the cupboard is close to the Potions Classroom or Snape's provisions cupboard.

Stink Bomb Store

The Stink Bomb Store is one of the rooms seen on the Marauder's Map. It is possibly an illegal store, because when a Hogwarts Professor bursts in the students inside it run out of the room. It is (possibly) the place where Stink Bombs and Dungbombs are sold.

Serpentine Corridor

This is a wide, curved corridor in the Hogwarts Turris Magnus at Hogwarts Castle. One can access the Defence Against the Dark Arts, the Ghoul Studies and Arithmancy Classrooms through this corridor, as well as Lost Wands.

Behind the scenes

"When it came to the third film, Alfonso really wanted to put his mark on the films. And then a lot of things altered: anything from character looks, to the actual layout of Hogwarts itself."

— Warwick Davis

Hogwarts castle as depicted on the back book cover of Harry Potter and the Half-Blood Prince Signature-edition

• When explaining the concept of Legilimency to Harry Potter, Snape said that many ancient spells and charms guard the Hogwarts walls and grounds, ensuring the inhabitants safety.
• It's seen that the interiors are not equal to exteriors of Hogwarts. (Ex: Curved walls inside, straight walls outside. Wide inside, narrow outside.) But this is possibly because Hogwarts is supported by magic.
• Hogwarts has different architecture in every adaptations and illustrations: Gothic the film adaptation, Medieval in the first three games and Mary GrandPre's illustration, Japonism in Kazu Kibuishi's, Flamboyant/Romanesque in Pottermore, and another different styles according to the version. But it is possibly it has its own unique architecture as Hogwarts is supported by magic, making it unique.
• It is revealed in Pottermore that Hogwarts Castle is the most haunted place in Great Britain. The castle is home to 20 or more ghosts.
• In the film adaptation of Harry Potter and the Chamber of Secrets, the entrance to Dumbledore's office is located in the Middle Courtyard, but in the video game adaptation of Harry Potter and the Half-Blood Prince, the entrance is located next to the Viaduct Courtyard. In both locations, the gargoyle must have to move quite a way to get to the tower or possibly there could be some kind of magical short-cut.
• Pottermore has a Feature on designing Hogwarts Castle.

Differences between books, films, and video games

Throughout the Harry Potter films, Hogwarts Castle has changed significantly:

Harry Potter and the Philosopher's Stone

Hogwarts in Philosopher's Stone

In the Philosopher's Stone film, only the parts of the castle that were needed for the film were created. This means that many areas of Hogwarts were missed. Areas of the castle included in the film were:

• The Great Hall
• The Grand Staircase Tower
• The Chamber of Reception
• The Viaduct
• The Viaduct Entrance
• The Central Tower
• The Bell Towers
• The Defence Against the Dark Arts tower
• The Training Grounds Tower
• The Transfiguration Courtyard
• The Quad
• The Training Grounds
• The Stone Bridge
• The Suspension Bridge
• The Boathouse
• Hagrid's Hut
• The Quidditch Pitch

Harry Potter and the Chamber of Secrets

Hogwarts Castle in the Chamber of Secrets

In the Chamber of Secrets film, there are a few small changes:

• The Training Grounds Tower's design has been changed, it now looks similar to the Clock Tower, only without the clock.
• The Training Grounds have been redesigned to have a more ruined aged design.
• The Greenhouses are added to the east corner of the castle below the Bell Towers.
• The Whomping Willow is added to the Training Grounds. It is possible that it was there in Philosopher's Stone, but it was never shown.
• A new staircase to the ground similar to the Boathouse staircase is added to the left side of the Chamber of Reception. It is possible that it was there in Philosopher's Stone, but it was never shown.
• A trench is added to the Quidditch stadium.

Harry Potter and the Prisoner of Azkaban

Hogwarts in the Prisoner of Azkaban

In the Prisoner of Azkaban film, there are some drastic changes that probably came about because of the new director, Alfonso Cuarón. But, the main shape of Hogwarts is still there:

• The Clock Tower, Clock Tower Courtyard, the Wooden Bridge, the North Tower and Sundial Garden are added to the back of the castle.
• The new stair from the Chamber of Reception is removed
• The Central Tower and Bell Towers now have taller, more gothic shapes.
• The Dark Tower is added in between the DADA Tower and Central Tower.
• Hagrid's Hut is moved down the hill at the back of the castle and a Pumpkin Patch is added.
• The Whomping Willow is moved from the Training Grounds to slightly down the hill from the Sundial Garden and off the path toward Hagrid's hut.

Inside the castle there are the following changes:

• Dumbledore's Owl Podium makes its first appearance in this film.
• The bronze statue of the Hogwarts Architect in the Entrance Hall has been removed (though it returns in the fifth film).
• The extra corridor connecting the Entrance Hall to the Grand Staircase has been removed. The Grand Staircase is now directly connected to the Entrance Hall.
• The entrance to the Gryffindor Common Room is moved to the Grand Staircase.
• The Grand Staircase is made higher, and now has 10 stories.
• The furniture in the Gryffindor Common Room has been re-arranged and there are more portraits on the wall in this film than in the others. This is due to a scene which was cut from the final film in which Sir Cadogan moves through the portraits and talks to Professor McGonagall.

Harry Potter and the Goblet of Fire

Hogwarts in the Goblet of Fire

In the Goblet of Fire film, there are the following changes:

• The Owlery is added on a hill behind the castle.
• A path from the Boathouse to the Quad is added.
• A new entrance to the Quad is added.
• The Quad no longer has the grass verges, and is now a paved courtyard.
• The Viaduct Courtyard replaces the Chamber of Reception, which is still wrongly seen in some scenes.

Inside the castle there are the following changes:

• In the Great Hall, the raised wooden platform on which the Staff Table sits is modified slightly. A second, higher section is added, allowing for a second table to be placed in front of the existing one. This table appears to be where the people in charge of the Triwizard Tournament sit. The table disappears following this film, but the second raised section remains.
• In the Entrance Hall, the door leading into the Chamber of Reception is replaced with two large wooden doors that connect the Entrance Hall to the Viaduct Courtyard.
• The cabinets in the Headmaster's Office receive a slight makeover. They now have glass in the doors (as opposed to grilles). Also the Pensieve Cabinet has been added.

Harry Potter and the Order of the Phoenix

The Order of the Phoenix film sees the least changes as nothing noticeable happens to the castle. However:

• The cones on the four smaller towers in front of the Central Tower are made taller.
• Cones are added to the turrets of the Clock Tower Courtyard.
• The Sundial Garden was removed from the entrance to the Wooden Bridge and is now seen lined up behind Hagrid's Hut.

Harry Potter and the Half-Blood Prince

File:Hogwarts Castle in Half-Blood Prince.png

In the Half-Blood Prince film, there are two major changes from the earlier films:

• The Astronomy Tower is added which means that the D.A.D.A. Tower and Dark Tower are removed.
• The Training Grounds Tower is replaced by another smaller bell tower.
• The Entrance Gates are added further down the hill to the back of Hogwarts. It is possible that these were present in the previous film adaptations but were not shown.
• The Central Tower has been shortened by one story to make the new Astronomy Tower seem taller.
• Two towers instead of one are now placed on the left side of the Clock Tower Courtyard. The right side remained with one tower.
• The Quidditch Pitch was moved to the opposite side of the Wooden Bridge beyond Hagrid's Hut. It is possible this change was there before, but not seen until Half-Blood Prince.

Harry Potter and the Deathly Hallows: Part 2

Hogwarts Castle minutes before the Battle of Hogwarts

Hogwarts after the Battle of Hogwarts

While omitted from Harry Potter and the Deathly Hallows: Part 1 aside from a brief cameo appearance, once the film was released, it was shown that although the third film had the highest number of modifications to date, Deathly Hallows: Part 2 has arguably the highest number of changes to prominent features and locations in and around Hogwarts. The noticeable changes to the castle are as follows:

• Viaduct Courtyard: It has been enlarged. Also, an archway opposite to the Entrance Hall doors connects it to the Viaduct and the floor has been modified. A short flight of stone steps that lead up to the castle doors has also been added.
• Entrance Hall: The walls are filled with Statues of Armour. The Architect of Hogwarts statue is replaced by the First Headmaster of Hogwarts statue.
• Viaduct Entrance: The two main larger towers on either side of the entrance have been made taller.
• The Quad: The Stone Bridge Tower has been changed into a tower resembling the one on top of the Astronomy Tower. A bridge has been added to the tower, connecting it to a little tower overlooking the Quad.
• Boathouse: It has a new design.
• Viaduct: It no longer connects the courtyard with the Viaduct Entrance, but now to land on the other side.
• The Grand Staircase has changed and has now taken on the appearance of a much bigger Marble Staircase, as in the books, there are fewer portraits, and the stairs do not move.
• The Wooden Bridge was made longer.
• The central tower design has a little modification.
• The Great Hall is higher and a Hogwarts crest is added to the centre of the back window, although it was broken at the end of Half Blood Prince, so it could have been replaced.
• The structure connecting the Entrance Hall to the Grand Staircase Tower has been shortened by 1 floor and has two small windows looking out onto the courtyard as opposed to one large one.

It should be noted that the castle shown burning in the teaser poster is actually the look of Hogwarts in Half-Blood Prince.

Most of these modifications were made in order to make the castle more convenient for the battle scene in the film. Changes were also made to match the tone of the film, as many of the fanciful elements of the castle that were present in the previous films were removed to match the darker and more violent tone of the final film.

Many of these edits to the castle's layout throughout the films can be explained as the effect of the school's ability to change its architecture by magic. However, certain elements, such as the Ravenclaw Tower, can be considered to have always been a part of the castle and simply never seen until the film they are introduced in, and the movement of the Viaduct and the redesign of the Grand Staircase in Deathly Hallows. The grounds around the castle seem to have change great throughout the films too, most notably in Prisoner of Azkaban and Deathly Hallows Part 2.

The Wizarding World of Harry Potter

Hogwarts in The Wizarding World of Harry Potter

First Concept Art of Hogwarts WWHP

Final Concept Art of Hogwarts WWHP

A castle has been built in Universal Orlando Studios for the Forbidden Journey in the "Wizarding World of Harry Potter Theme Park". It includes:

• The Great Hall
• The Grand Staircase Tower
• The Astronomy Tower
• The Viaduct and Viaduct Entrance
• The Viaduct Courtyard and the Stone Bridge
• Hagrid's Hut and the Whomping Willow
• Filch's office

Although it is based on the castle seen in Half-Blood Prince, most of it is missing and it differs greatly from the one seen in the films:

• The Viaduct is not connected to the Viaduct Courtyard.
• The Entrance Hall is not connected to the Grand Staircase Tower.
• The Astronomy Tower takes the place of the Central Tower.
• The Stone Bridge is only connected to the Grand Staircase Tower not the right Viaduct Entrance Tower.
• The stone bridge took the place of an archway building connecting the Grand Staircase Tower to the Stone Bridge Tower.
• Elements such as the Boathouse, the Sundial Garden, and the Wooden Bridge are missing.
• The Great Lake is also missing, but this is understandable as the lake takes up a great deal of space around the castle that was unavailable to the park. Also, it was required that the castle be easily accessible to visitors.

Harry Potter and the Forbidden Journey

The castle seen during the ride is Hogwarts as seen in Half-Blood Prince, but there are some differences:

• The new Boathouse from Deathly Hallows is added.
• A skinnier version of the new tower seen in the Deathly Hallows trailers, adjacent to the Stone Bridge Tower, can be seen.

The Queen's Handbag

The castle seen here is the same as seen in the first film.

LEGO Harry Potter: Years 1-4

Hogwarts in the LEGO Harry Potter game seems to be based on the castle seen in Prisoner of Azkaban, although it is based on the first four films. Presumably this is because it includes the Entrance Hall Antechamber which only appears in the first three films; also, the Central and Bell Towers have the shape used from the third film onwards. However, the Clock Tower is not connected to the castle like in the films. Additionally, it seems that the Whomping Willow will change location from the second to third year as it does in the films. The North Tower also receives its own courtyard, the North Tower courtyard.

LEGO Harry Potter: Years 5-7

Hogwarts in LEGO Harry Potter: Years 5-7 seems to be based on the castle seen in Harry Potter and the Deathly Hallows: Part 2. However, there are some differences. The Astronomy Tower does not overlook the Middle Courtyard, and the Dark Tower is there instead, last seen in Harry Potter and the Order of the Phoenix (film). The Boathouse, the Training Grounds Tower and the Stone Bridge tower remain unchanged, and there are two Viaducts: one connecting the Viaduct Courtyard to the Viaduct Entrance, and the other connecting the same courtyard to the grounds, as it does in the last film adaptation. Despite that, the two checkpoint towers are not there. Finally, the Defence Against the Dark Arts tower is still there.

Harry Potter: Hogwarts Mystery

The Hogwarts Castle shown in cutscenes, etc. are from the film adaption of Harry Potter and the Half Blood Prince. However, there are some changes present:

• The suits of armour is present in the Entrance Hall
• Hagrid's Hut is just off the Training Grounds

Fantastic Beasts: The Crimes of Grindelwald

Hogwarts in Fantastic Beasts: Crimes of Grindelwald

The Hogwarts shown in Fantastic Beasts: The Crimes of Grindelwald is based off of the design set in Harry Potter and the Deathly Hallows: Part 2 prior to The Battle of Hogwarts

Design Mistakes Between Interiors and Exteriors

The castle was not designed as a perfect marriage between the exterior models and the interior film sets. While great efforts were made to design a seamless castle, many mistakes were made. These have resulted in real-life problems when trying to make models of the castle that include the interiors. The developers of the tie-in video games sometimes created interiors that could not possibly fit inside the exterior walls. Starting with Harry Potter and the Order of the Phoenix (video game), the interior of the castle was designed to precisely match what was seen in the corresponding film.

Harry Potter and the Philosopher's Stone (film)

• The Great Hall is positioned much higher than it should be. As a result, the Chamber of Reception is positioned far too low for corresponding interior to meet at the Great Hall's floor level. It is therefore impossible for the Chamber of Reception's stairs to get high enough to connect to the Entrance Hall.
• The side windows of the Chamber of Reception do not exactly match the corresponding windows on the model.
• The small staircase behind the staff table in the Great Hall is architecturally impossible because the exterior wall is right where the door opens.
• The Gryffindor Common Room's film set does not match the model. There is a window to the left of the fireplace than cannot possibly fit unless the entire area protrudes from the rest of the Quad by more than several metres. This area is only shown to protrude a metre or two on Harry Potter and the Goblet of Fire (film)'s model.
• Despite the need for a dormitory for each gender by year, the Gryffindor Common Room shows that there are only two rooms, and Harry's year lives in the same boys' room every year. There should be at least fourteen rooms in total.
• The Library's windows do not match up. The smaller windows on the side should be lower and taller on the model.

Harry Potter and the Chamber of Secrets (film)

• The new film set for the Hospital Wing was introduced without it being represented by the exterior model of the castle.
• There is no tower that supports the shape or windows of the Defence Against the Dark Arts Classroom.
• The entrance to Dumbledore's office is shown to be near the Middle Courtyard, despite the office being located at the top of the Marble Staircase Tower.
• The Middle Courtyard as shown at the end of the film is architecturally impossible. Sunlight can be seen from both sides of the roofed pathway and the end of the pathway shows the valley area, despite the entire courtyard being surrounded by the castle.

Harry Potter and the Prisoner of Azkaban (film)

• The Entrance Hall has a new, larger window to the left that is not represented on the exterior model. The model uses the architecture from the previous two films, which had the Entrance Hall's window represented by the fourth window (in the lower set) of the Chamber of Reception building. That other window is also still on the model.
• The Grand Staircase is now directly connected to the Entrance Hall. However, this is impossible on the exterior model, which retains the link building from the previous films that is much lower than the Great Hall's window level. In fact, the Great Hall building's lower balcony (which is at the floor level of the Hogwarts kitchens) also partly serves as the roof of the link building.
• The new location of the Gryffindor Common Room at the top of the Grand Staircase does not fit the shape of the Marble Staircase Tower.
• The Clock Tower is only connected to the rest of the castle by the Hospital Wing. This means that the only way to physically access the clock tower would be to go to the back of the Quad and go up a small set of stairs that lead up to directly outside the Hospital Wing. It is possible that there are secret passages or portrait passages used by students in universe.
• The big window in the back of the Grand Staircase room is shown to have moved inward so that it lines up with the wall. However, this is impossible because blueprints show that that Quad has extra space between the room's wall and the exterior, meaning that the window must be outward from the Grand Staircase room's wall like it was in the first film.
• The Divination classroom appears to be too large to fit inside the top of the North Tower.
• The Divination stairwell's windows require that it be located inside a small circular tower, none of which exist on the model in the correct location.

Harry Potter and the Goblet of Fire (film)

• With the addition of the Viaduct Courtyard, the designers forgot to add the stairs up to the Great Hall that were previously represented by the Chamber of Reception. As a result, the Great Hall is now positioned lower than it had been previously. The designers also forgot to adjust the windows to make the exterior model match the film set. The model has the smaller set of windows at the bottom, while the film set only has the larger set of windows. It is believed that the smaller set of windows were originally designed to represent the Hogwarts Kitchens, but that area was never seen in the films. This issue remained unfixed until Harry Potter and the Deathly Hallows: Part 2.
• The new model also added a connector hallway between the Entrance Hall and the Grand Staircase. This is not seen at all in the films until Harry Potter and the Deathly Hallows: Part 2, where its size was decreased.
• There is no tower that supports the shape and windows of the new Defence Against the Dark Arts staircase.
• Despite Harry's dormitory being shown as the highest one in the tower but being on the same level as the girl's dormitory, the model's version of the tower has at least one extra floor that exceeds the height of the corresponding area where the girls' dormitories are.

Harry Potter and the Order of the Phoenix (film)

• There is no part of the castle's exterior that directly corresponds with the hallway (Hall of Hexes) near the Room of Requirement's entrance.

Harry Potter and the Half-Blood Prince (film)

• The Potions classroom was redesigned to be in a plus shape. This version has windows on eleven of the twelve sides. This is impossible, not only because it is housed in a circular tower, but because many of the sides are blocked by terrain and thus cannot have windows emitting light. Only the window in the back of the room is possible, and it was shown in the Occlumency establishing shot in Harry Potter and the Order of the Phoenix (film).
• The close-up establishing shot of the Astronomy Tower shortly after Ron's Quidditch victory appears to use a different model than the full-castle one that has differing details. The windows are bigger with a different pattern (and are closer to the top) and it shows a protruding spiral staircase on the right side of the rear. The main model has smaller windows and only a protruding tower on the left side of the rear. The interior set for this scene also seems to suggest that there is some kind of courtyard inside the Astronomy Tower.
• There are several hallways with windows resembling the Entrance Hall and Great Hall's windows that do not appear to match up with the exterior model at all.

Harry Potter and the Deathly Hallows: Part 2

• The exterior model fixes the Great Hall's corresponding window issue by switching the positions of the smaller and larger sets of windows. However, the interior film set did not change from the previous versions and thus does not include these windows, which should now be visible below the ceiling.
• Students from a house in which the dormitories are located on the east side of the castle are shown marching to the Great Hall through the Viaduct Courtyard, even though the viaduct bridge that connects the two areas together was removed.
• The redesign of the Grand Staircase shows that the area of the stairs far exceeds the area of the Marble Staircase Tower.
• There is no tower that supports the shape and windows of the narrow staircase that leads up to the Ravenclaw Common Room.
• The courtyard where Harry talks to the Grey Lady does not appear to correspond with any of the model's courtyards. It might be a new elevated courtyard surrounding the Quad, but its size is too small and its nearby windows do not match up with that Quad.
