Chamber of Secrets

Salazar Slytherin, one of the original founders of Hogwarts, created the Chamber of Secrets just before he left the school. It was built way below the dungeons of the castle and housed an ancient Basilisk which Slytherin intended to rid the school of its unpure students. The entrance is located in Moaning Myrtle’s bathroom and one must say “open” in Parseltongue to gain access. The sink then opens into a slide, and at the end of it, the person lands in a damp, stone chamber. The room is said to be “miles beneath the school,” situated somewhere below the Great Lake.
