Moaning Myrtle's bathroom
Floor 2 - Female Toilets
This girls' lavatory is situated on the second floor of the tower. It has been out of order ever since a student named Myrtle was killed there. Myrtle has haunted the bathroom ever since, leading it to be a place most students do not want to enter. This bathroom holds the entrance to the Chamber of Secrets. To get in the Chamber, a person needs to say "open" in Parseltongue. This will cause the tap with a snake on the side (a tap which incidentally, never worked) to move into the floor, revealing a tunnel which leads downwards into the Chamber.
