 Common Room
The Ravenclaw house common room is found behind a door of wood, with no handle or keyhole, only a bronze eagle shaped door knocker. To enter, you have to knock once and answer the question the eagle asks you, unlike other houses, which only have a password. You have to answer the question correctly in order to get inside, but if you get it wrong you have to wait for another Ravenclaw to come along and answer a question. The common room is a wide and circular room, with arched windows that are hung with blue and bronze silks. The celing is painted with stars, and the carpet is blue. There are also several tables, chairs and bookcases that line the walls. Opposite the door is a tall statue of Rowena Ravenclaw, made of white marble.
