The Astronomy Tower was the tallest tower at Hogwarts Castle. It was where students studied the stars and planets through their telescopes in Astronomy lessons with Professor Aurora Sinistra. This was usually done at midnight, when the stars were best seen.[1] The tower was generally out-of-bounds except for classes.[1]



Exterior view of the tower

In Harry Potter's first year, he and Hermione Granger climbed to the top of the Astronomy Tower to send Rubeus Hagrid's pet dragon, Norbert, to Charlie Weasley in Romania. Despite their success in sending Norbert away, they were caught by Argus Filch when they descended the tower, because they had forgotten to bring Harry's Invisibility Cloak back with them.[2] Professor McGonagall also caught Neville Longbottom and took away 150 points from Gryffindor house.[3]


After Sirius Black tried to break in to the Gryffindor Tower on the evening of 31 October, 1993, all the staff was to search the Castle for any signs of Black. Argus Filch searched the Astronomy Tower and found nothing.[4]


The O.W.L. Astronomy exam in 1996

The Astronomy practical exam took place here for the O.W.L.s. Under the supervision of Professor Tofty, students were required to fill out a star chart. However, Dolores Umbridge, John Dawlish and several other Ministry of Magic officials attacked Rubeus Hagrid during this practical, and the resulting skirmish caused several Aurors and Professor Minerva McGonagall to be severely injured, Fang too become incapacitated, and Hagrid was forced to flee the school. All of this was witnessed by the Fifth years taking their Astronomy O.W.L.s.[5]


Harry and Dumbledore at the Astronomy Tower in 1997

When the Death Eaters arrived at Hogwarts, most of the Battle of the Astronomy Tower between the opposing sides took place in this tower, and in the corridor below. Death Eaters set off the Dark Mark above this tower; Albus Dumbledore was blasted from the tower's ramparts by a Killing Curse cast by Severus Snape.[6] This was where Dumbledore met his death,[6] by his own orders.[7]


The Tower from behind

The tower is the tallest in Hogwarts, it lies almost directly above the front doors of the castle. The tower is also surrounded by a parapet and is tall enough to have a perfect view of the starry sky.[1]
