The entrance to the common room is located on the west side of Hogwarts at the top of a spiral staircase, located on the fifth floor, and is a door without a doorknob or keyhole, but a bronze knocker in the shape of an eagle. In order to enter the room, a person must answer a riddle asked by the eagle knocker; if they answer incorrectly, they must wait for someone else who gets it right. The entrance to the Ravenclaw dormitories are also located in the Tower, beside a statue of Rowena Ravenclaw.
