Overview

The Hogwarts Dungeons are the underground levels of Hogwarts Castle, extending beneath the ground floor. Cold, damp, and dimly lit, the dungeons house the Potions classroom, the Slytherin common room and dormitories, various storerooms, and the entrance to the Chamber of Secrets. The dungeons' stone walls and floors create an atmosphere quite different from the rest of the castle, contributing to Slytherin House's distinctive character.
