The Slytherin common room and dormitories are located in Slytherin Dungeon. Students enter the Dungeon through a concealed stone wall. They must present the correct password (it changes every fortnight) to open the wall and reveal the entrance to the common room.
Slytherin’s common room looks out into the depths of the Hogwarts lake. The Giant Squid and other interesting aquatic creatures often pass by the windows. It has the feel of a mysterious, underwater shipwreck, but it is still quite cosy.
The dormitories have ancient four-posters with green and silk hangings and bedspreads embroidered with silver thread. Medieval tapestries depicting the adventures of famous Slytherins hang from the walls. The light comes from silver lanterns hung from the ceilings.
