The Astronomy Tower is the tallest tower at Hogwarts Castle surrounded by a parapet. 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.



In Harry Potter's first year, he and Hermione Granger climbed to the top of the Astronomy Tower to give Rubeus Hagrid's pet dragon, Norbert, to Charlie Weasley to take care of in Romania.


When the Fat Lady's portrait, the one that attached in the door entrance to the Gryffindor common room was attacked by a transformed Sirius Black, Gryffindors students couldn't enter. They had to use the Astronomy tower for the room replacement until the door was fixed. Later, Remus Lupin, the Defence Against the Dark Arts professor during that school year used this tower to teach Harry Potter how to perform a Patronus Charm.

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. This was where he met his death.[1]


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 site of the starry sky.
