Number First-Floor•Girls'-Lavatory Tower

This tower was part of Hogwarts Castle. It was located at the back of the left Viaduct tower, adjacent to the Viaduct Entrance. The second floor of the tower hosted a girls' lavatory.

===Myrtle's bathroom===
This girls' lavatory was situated on the first floor of the tower. It had been out of order ever since a student named Myrtle Warren was killed there. Myrtle had haunted the bathroom ever since, leading it to be a place most students did not want to enter. This bathroom held the entrance to the Chamber of Secrets. To get in the Chamber, a person needed to say "open" in Parseltongue. This would cause the entire section of the sink with the tap with a snake on the side (a tap which incidentally, never worked) to move into the floor, revealing a tunnel which led downwards into the Chamber.
==Behind the scenes==
*Despite how the tower seems small and off-centred, the lavatory seems exceptionally large and key-hole shaped. However, this may be supported with magic.
