Ravenclaw Tower

The Ravenclaw Tower is located on the west side of Hogwarts, the staircase leading up to the common room is located on the fifth floor. One climbs up these staircases to get to the Ravenclaw common room and dormitories. The entrance to the room is at the top of a spiral staircase, and is a door without doorknob or keyhole but a bronze knocker in the shape of an eagle. In order to enter the room, you must answer a question asked by the eagle knocker; if you answer wrong, you must wait for someone who gets it right.
