Gryffindor Tower is the main residence for the Gryffindors in Hogwarts. The path from the entrance hall goes up several flights of stairs and passes through more than one concealed door. The main entrance to the tower is concealed behind the painting of the Fat Lady, who requires a password of anyone desiring to enter. Its resident ghost is Nearly Headless Nick.
Inside the tower is a common room with a fireplace and cozy furniture, and separate dormitories for boys and girls, with up to five four-poster beds to a room.
