The Chamber of Secrets
The Chamber of Secrets was created under the dungeons of Hogwarts School of Witchcraft and Wizardry during Medieval times by Salazar Slytherin, who disagreed with the other Hogwarts on the merits of blood purity. The Chamber of Secrets was home to an ancient Basilisk, which, according to legend, was intended to be used to purge the area of Muggle-born students. The Chamber is flanked with towering pillars entwined with carved wood, and a tall statue of Salazar Slytherin is at the far end. The basilisk rests within the mouth of the statue, possibly symbolizing Salazar Slytherin's ability to speak Parseltongue.
