"I think the Slytherin common room has a spooky beauty."
-- J.K. Rowling (TLC)
The Slytherin common room is a long, low-ceilinged, dungeon-like room filled with skulls and the like. There are high-backed chairs and a carved mantelpiece on the fireplace. The walls are rough stone. The light is green from the green hanging lamps and because it’s located under the lake (CS12, DH23).
Gemma Farley, a Slytherin Prefect, describes the common room in her introduction to the House:
“Our emblem is the serpent, the wisest of creatures; our house colours are emerald green and silver, and our common room lies behind a concealed entrance down in the dungeons. As you’ll see, its windows look out into the depths of the Hogwarts lake. We often see the giant squid swooshing by – and sometimes more interesting creatures. We like to feel that our hangout has the aura of a mysterious, underwater shipwreck” (Pm)
