The Chamber of Secrets

Buried deep within Hogwarts lay the Chamber of Secrets. It was created by Salazar Slytherin, unbeknownst to the other Hogwarts founders, and was believed to be a myth for centuries. The entrance to the Chamber was in the girls’ toilets on the second floor and it could only be opened by those who could speak Parseltongue. It was also home to a Basilisk, a giant snake that could only be controlled by Slytherin or his heirs.
