The Chamber of Secrets

The Chamber of Secrets was allegedly created deep under the dungeons of Hogwarts Castle during the Medieval times by Salazar Slytherin, who disagreed with the other Hogwarts Founders on the merits of blood purity. The Chamber of Secrets was home to an ancient Basilisk, which was intended to be used to purge the school of Muggle-born students. The entrance can be found in Moaning Myrtle's bathroom on the second floor. In order to gain entrance one must say "open" in Parseltongue and a sink will open into a slide. While falling down the large, dark pipe, one can see hundreds of other pipes leading off. At the end of the pipe, one is launched into a damp, stone chamber.
