Astronomy Staircase

The Astronomy Staircase was a staircase in Hogwarts Castle which led to the Astronomy Classroom at the top of the Astronomy Tower, the tallest tower at Hogwarts. This was the staircase where The Battle of the Astronomy Tower started, and Albus Dumbledore was murdered. Being caught on the staircase, or any part of the tower at that matter, besides during classes, will result in detention.
