"It's ideal for Headquarters, of course. My father put every security measure known to wizardkind on it when he lived here. It's unplottable, so Muggles could never come and call — as if they'd ever have wanted to — and now Dumbledore's added his protection, you'd be hard put to find a safer house anywhere."
Sirius Black regarding 12 Grimmauld Place[src]

12 Grimmauld Place was the ancestral home of the Black family, located in the Borough of Islington, London, in a Muggle neighbourhood, and the location was protected by a Fidelius Charm. As the house was invisible to the neighbourhood residents, the local Muggles had long since accepted the mistake in numbering which landed number 13 next to number 11.[1]

In 1995, the home became the headquarters for the Order of the Phoenix with the consent of Sirius Black,[1] with Albus Dumbledore becoming Secret Keeper. After Dumbledore's death in 1997, everyone in whom he confided the location of 12 Grimmauld Place became a Secret Keeper, so the headquarters was moved to the Burrow.[4]


Early history[]

"Tucked away in northwestern London, a twenty minute walk from King's Cross Station, lies number twelve, Grimmauld Place. Both Unplottable and hidden behind a Fidelius Charm, the house is invisible to all but a few. Though the neighbouring Muggles don't even know the building exists, it was for many years home to the Black family — one of the wizarding world's oldest pureblood families, and extremely proud to be so."
— Description of the house[src]

Number 12 Grimmauld Place was formerly a handsome Muggle townhouse built in London. At some point, an early member of the wizarding House of Black coveted the beautiful house and managed to "persuade" the original Muggle occupant to leave, and put the appropriate spells on it.[3]

Under Orion and Walburga Black[]

12 Grimmauld Place was, apparently, in the Black family for some generations when Orion and Walburga Black took possession in the mid-20th century. Sirius and Regulus Black grew up in the house. Sirius ran away from home around 1976 at age sixteen, and both Regulus and Orion died just a few years later, in 1979. This left Walburga living in the house alone with the family house-elf, Kreacher. Upon Walburga's death in 1985, the house passed to her only living descendant, Sirius, who, though he had been blasted off the family tree, had apparently not been disinherited.[5]

Since Sirius was in Azkaban, the house sat empty for ten years with only Kreacher, who had gone "round the twist", to look after it. Walburga Black made her disgust of having anyone less than pure-blood in her home very clear through the hostile shrieks of her portrait, which was affixed to the wall with a Permanent Sticking Charm.[5]

Sirius Black stated that the house was unoccupied after the death of his mother Walburga in 1985.[5] The Black family tree shows that both of Sirius's grandfathers, Arcturus Black III and Pollux Black, survived Walburga by several years, as did his unmarried great-aunt Cassiopeia, so they must have lived elsewhere.

Sirius Black, Walburga's son, hated number 12 Grimmauld Place, and left when he was sixteen. He never imagined he would have to return to his family's home.[1] During Sirius's imprisonment in Azkaban, wrongly convicted for the crime of murdering twelve Muggles and Peter Pettigrew (Pettigrew being the real perpetrator),[6] the house was unoccupied, besides the Black family's house elf, Kreacher.

After his escape in 1993,[7] Sirius gave the home over to the Order of the Phoenix to be used as a headquarters. The home required an arduous cleaning up to make it even remotely habitable. Much of this work fell to Molly Weasley and her children. The home was in such disrepair that doxies and boggarts had made themselves quite at home.[5][8][9]

Following Sirius's death in 1996, the Order temporarily vacated the building for fear that its ownership had passed to his cousin, Bellatrix Lestrange; however, it soon proved that Sirius had successfully left the house to Harry Potter in his will, and with his blessing the Order moved back in once again.[2]

Under Harry Potter[]

The Order of the Phoenix[]

After Sirius Black was murdered by Bellatrix Lestrange in 1996 during the Battle of the Department of Mysteries,[10] the house was inherited by his godson, Harry Potter. He continued to allow the Order of the Phoenix to use it as a safe house.[2] After the death of Albus Dumbledore, Grimmauld Place's Secret Keeper in 1997, each of the members of the order to whom the secret had been imparted became Secret Keepers themselves, giving them the power to reveal the house to others.[4]

The Secret Keepers included Severus Snape, who had killed Dumbledore and was believed to be in Lord Voldemort's employ and therefore would allow Death Eaters into the Order's headquarters. Alastor Moody placed a number of protective enchantments on the house to keep Snape from entering.[11]

These were a Tongue-Tying Curse to prevent him from telling others of the place and a dust-composed form of Dumbledore, which disintegrated when the person it advanced upon said the word kill or a variant, the point of this being that Moody believed that Snape would be too overrun with guilt to say that he had killed Albus, forcing him to retreat.

However, the Order did not know that Dumbledore's death was prearranged with Snape. Despite these enchantments, the Order ceased use of the house as headquarters as they still could not risk being ambushed by Death Eaters.[11]

When Harry Potter, Ron Weasley, and Hermione Granger escaped from the Death Eater attack on Bill Weasley and Fleur Delacour's wedding ceremony on 1 August 1997, they hid at Grimmauld Place. They were able to remain hidden there for a month, though Death Eaters, who were staking out locations linked to the Order, skulked about the street outside, unable to see the secret location.[11]

While at Grimmauld Place, the trio learned that Kreacher had attempted to destroy Salazar Slytherin's Locket one of several Horcruxes created by Lord Voldemort at the request of his master, Regulus Black. Kreacher revealed that the Horcrux was stolen by Mundungus Fletcher during a looting of 12 Grimmauld Place. After presenting Kreacher with Regulus Black's locket, Harry asked Kreacher to track down Mundungus.[12]

Kreacher returned days later with Mundungus, who revealed that the locket was taken by Dolores Umbridge in Diagon Alley. The trio hatched a plan to infiltrate the Ministry of Magic. While performing four weeks of stakeouts at the Ministry entrance, they spent some of their free time cleaning up 12 Grimmauld Place.[12]

After retrieving Salazar Slytherin's Locket from Umbridge, they Apparated back to Grimmauld Place, but Corban Yaxley grabbed Hermione's arm in the process. She struck him with a Revulsion Jinx and Disapparated away with Harry and Ron, but the house's location had been revealed to Yaxley, and they were forced to abandon it.[13]

It's unknown what happened to Grimmauld Place when the Second Wizarding War was over, but even though Harry was not living in it, it's possible that it was kept safe for the Order of the Phoenix.

Security measures[]

12 Grimmauld Place is hidden from view

By the time the Order of the Phoenix made 12 Grimmauld Place its headquarters, the house had been placed under "every security measure known to wizard-kind". Among other things, the house is Unplottable, which makes it accessible only to wizards, and had spells on the front door such that it could only be unlocked by a wizard using his or her wand.

The house was also placed under a Fidelius Charm, meaning it couldn't be accessed by wizards, either, unless they were told its location by the Secret Keeper.[1] Albus Dumbledore was the Secret Keeper for Grimmauld Place until his death in 1997, after which everyone who had been told the secret became a Secret Keeper themselves.[4]

Dumbledore's death also led Mad-Eye Moody to place additional enchantments on the house, in order to prevent Severus Snape from accessing it: he set up a Tongue-Tying Curse that sensed whether a person entering the house was Snape, and if so, bound his tongue; and a Dumbledore figure, made of dust, that approached intruders unless they tell it that they were not the one who killed Dumbledore.[11]


Front entrance[]

When a wizard who knew of its location approached number twelve, Grimmauld Place, it appeared to shove its neighbouring houses, number eleven and number thirteen, out of the way as it appeared between them. The house had a worn set of front steps leading to a battered front door. On the door was a silver knocker in the shape of a twisted serpent but it had no keyhole, handle, or anything else that would indicate it to be a door, as it opened only by magic.

There was a doorbell — a "loud, clanging bell" that tended to awaken Walburga Black's portrait inside. When one left the house, the building vanished behind them the instant they reached the street.[1]

Ground floor[]

"He could smell damp, dust and a sweetish, rotting smell; the place had the feeling of a derelict building... old-fashioned gas lamps sputtered into life all along the walls, casting a flickering insubstantial light over the peeling wallpaper and threadbare carpet of a long, gloomy hallway, where a cobwebby chandelier glimmered overhead and age-blackened portraits hung crooked on the walls."
— The front entrance of Grimmauld Place[src]
12 Grim Place

The front door opened into a long hallway, lit with gas lamps and a large overhead chandelier. It was described as having been a grand entryway at one time, complete with ornate portraits on the walls, but by the time Harry first visited the house it was gloomy and cobwebby, with the wallpaper peeling off and the carpet worn thin.[1]

Of all the portraits, the most prominent was an enormous portrait of Walburga Black, stuck to the wall via a Permanent Sticking Charm, which had taken to screaming at the top of her lungs whenever she spotted "Mudbloods", "blood traitors", and "half breeds" in her house.[1][5] This caused frequent annoyance to the members of the Order of the Phoenix during their occupation, as the organisation was completely composed of such individuals.

The Order covered the portrait with a curtain to attempt to minimise her attention but any loud noise would wake her again. Much of the decor in the entry hall was in the form of serpents, though there was also an umbrella stand made from the severed leg of a Troll, that Nymphadora Tonks was particularly prone to knocking over. This had the unfortunate effect of frequently waking up the portrait and starting her screams again.[1]

Grimmauld Place Dining Room

The dining room at 12 Grimmauld Place

On one side of the hallway was the dining room, which contained a long wooden table with chairs and hanging light fixtures. It also featured a dresser holding the Black family crest and china. At some point while the house was abandoned, spiders the size of saucers moved into the dresser. Harry, Sirius, and the Weasley family cleaned these out during their summer at Grimmauld Place; however, Ron Weasley didn't help much due to his arachnophobia.[8]

At the end of the entrance hall, facing the door, a grand staircase lead to the upper floors of 12 Grimmauld Place.[11] The wall on the stairs was decorated with a row of shrunken house-elf heads, mounted on the wall on plaques. These were former servants of the House of Black who had been beheaded when they had become too old to hold a tea-tray; a tradition begun by Elladora Black.[1]


"It was scarcely less gloomy than the hall above, a cavernous room with rough stone walls. Most of the light was coming from a large fire at the far end of the room. A haze of pipe smoke hung in the air like battle fumes, through which loomed the menacing shapes of heavy iron pots and pans hanging from the dark ceiling. Many chairs had been crammed into the room for the meeting and a long wooden table stood in the middle of the room, littered with rolls of parchment, goblets, empty wine bottles, and a heap of what appeared to be rags."
— Description of the kitchen of Grimmauld Place[src]

A door at the far end of the entry hall, a set of narrow stone stairs leads to the basement, and the house's kitchen. Though less ornate than the floors above, the kitchen was still a large, "cavernous" room with a large fireplace at the far end. Iron pots and pans hung from the ceiling above, and a long wooden table sits in the centre of the room, large enough to fit a couple dozen people around it for a meal. The room had a gloomy feeling when it was occupied by the Order of the Phoenix,[8] but when Harry later lived in the house, Kreacher cleaned the room up and made it sparkling, "almost unrecognizable" as the same room where the Order once held its meetings.[14]

Also in the basement, just off the kitchen, was a dark pantry, large enough for two people to stand in comfortably; and another cupboard off the kitchen housed the boiler for the house, as well as Kreacher's den, filled with rags, smelly blankets, and photographs of the Black family.[5]

First floor[]

"...entered the drawing room, a long, high-ceilinged room on the first floor with olive-green walls covered in dirty tapestries. The carpet exhaled little clouds of dust every time someone put their foot on it and the long, moss-green velvet curtains were buzzing as though swarming with invisible bees."
— Description of the drawling room[src]

On the first floor, there are at least three rooms: a bedroom, where Hermione and Ginny once slept; a bathroom where Harry once ran when he was overcome with a vision of Voldemort; and, of the most significance, the drawing room.[1][5]

The drawing room was at one time exquisite, with large windows overlooking the street in front of the house, a large fireplace flanked by two ornate glass-fronted cabinets, and an entire wall covered with a tapestry of the Black family tree. In the summer of 1995, though, the room mostly just needed a good cleaning, as the curtains were filled with doxies, the writing desk housed a Boggart, and the dark items in the cabinets — from snakeskins to bottles of blood to boxes of Wartcap powder — were ready to put up a fight against anyone trying to clean them up.[8]

It was in this room that Kreacher stored Slytherin's locket when he couldn't get it open,[12] and it was in this room that Harry, Ron, and Hermione slept (Hermione on the sofa cushions) when they returned to the house two years later to hide from the Ministry.[11]

Upper floors[]

"The bedroom looked, if anything, even danker and gloomier than it had on first sight. The blank picture on the wall was now breathing very slowly and deeply, as though its invisible occupant was asleep."
— Description of one of the upper bedrooms[src]

The second floor housed at least one bedroom, and possibly more. It was in this room that Harry and Ron slept during their first stay at Grimmauld Place. The room had two twin beds and a wardrobe, and like the rest of the house was gloomy, had lofty ceilings, and had a doorknob in the shape of a serpent.[1] On the wall was a portrait of Phineas Nigellus Black (though Hermione later removed this),[14] and in the corner there was a wastebasket that coughed when owl droppings were placed in it.[9]

From the landing on the second floor, it was possible to look down over the banisters and see the top of anyone's head who is standing in the front entrance hall.[1]

On the third floor, there was a mouldy cupboard that Harry, Ron, and Hermione had to clean out as well as at least three bedrooms. Fred, George, and Mr and Mrs Weasley all slept on the floor above Harry and Ron's bedroom, and Mrs Black's former bedroom, where Buckbeak stayed, must also have been on this floor since it is "upstairs" to both the drawing room and Harry and Ron's bedroom but not on the fourth floor with Sirius and Regulus's rooms.[8]

The topmost landing is probably the fourth floor, and on this floor were only two doors: one leading to Sirius's room, and the other to Regulus's. The latter was marked by a sign on the door — "Do Not Enter Without the Express Permission of Regulus Arcturus Black" — that eventually proved to be the clue Harry would need to discover the identity of R.A.B.

Though Harry Potter never entered either until he owned the house himself, he could tell that both rooms had once been beautiful, with carved wooden headboards on the beds, velvet curtains, and fine wall hangings and furniture.[15]

The decor in the two rooms, could not have been more different: Sirius decked his room out in Gryffindor colours and banners, and posters of Muggle motorbikes and bikini-clad girls. In Regulus's room, slightly smaller, the decor of course highlighted his Slytherin, pure-blood heritage, with a Black family crest painted over the bed and newspaper clippings about Voldemort donning the walls.[15]

There was also an attic where Kreacher claimed to have been when he was in fact at Malfoy Manor.


Slytherin's Locket PM

Salazar Slytherin's Locket, once in the possession of Regulus Black

Number 12, Grimmauld Place held many Black family heirlooms and possessions, such as a music box that played a sickly tune and tried to put the listener to sleep, crested goblets, a biting silver box containing Wartcap powder, and an unopenable locket which turned out to be Salazar Slytherin's Locket, one of Lord Voldemort's Horcruxes.[8] This was where Kreacher put the object after he drove himself mad not being able to complete his master's orders to destroy the locket because it had to be damaged past the point of repair, which was beyond the capabilities and understanding of the house-elf.[15]

Another object of note was the portrait of Walburga Black, which has an unpleasant habit of loudly screaming about the "Mudbloods" and "blood traitors" of the Order of the Phoenix members that inhabited the house, due to Walburga's prejudice against such people. The portrait was usually closed off with curtains, which aimed to keep the portrait quiet, but are not very effective; any loud noise in the vicinity would cause the curtains to fly open, and Walburga to start raging and howling again until someone forced the curtains shut.[1][5]


Harry Potter searching one of the bedrooms for the locket

Many of these family heirlooms were stolen and peddled by Mundungus Fletcher, including Salazar Slytherin's Locket, which the thief was forced to give to none other than Dolores Umbridge to avoid prosecution for trading without a licence, she used the locket to enforce her pure-blood credentials, claiming that the 'S' stood for Selwyn, which she claimed was a pure-blood family to whom she was related. In fact, the locket was an heirloom of Salazar Slytherin as well as one of Lord Voldemort's Horcruxes, which Regulus Black stole when he abandoned the Death Eaters.[12]

Known objects[]


The name is another of J. K. Rowling's puns: Grimmauld Place can be taken as "grim, old place" or "grim mould place." The house's owner for most of the books is also Sirius Black, whose Animagus form is confused for, and referred to as, "the Grim" throughout Harry Potter and the Prisoner of Azkaban.

Behind the scenes[]

  • The inheritance of the property by Sirius Black is almost certainly governed by the magical equivalent of the English Common Law concept of the Entailed Estate. Under this type of arrangement, the inheritance of the covered property by the designated heir ("down the direct line, to the next male with the name of 'Black'") cannot be prevented by disinheritance or any other legal means. The only way the entail breaks is if there is no living descendant who matches the conditions of the entail. When the entail breaks, the property in question can be disposed of by any legal means, including being willed to any person the current holder so chooses. This legal mechanism matches the known circumstances of the inheritance, where the property was inherited by Sirius although he was "disowned", and then could be successfully left to Harry Potter once there was no "direct line, male descendant".
  • In the films, Harry's inheritance of the house is omitted.
