The Ravenclaw common room is in one of the castle's towers and is wide and circular. It has graceful arched windows, and the walls are hung with blue and bronze silks. The domed ceiling is painted with stars, which are echoed in the midnight-blue carpet. Tables, chairs, and bookcases cover the expanse of the floor, and a white-marble statue of Rowena Ravenclaw sits next to the door that leads to the dormitories above. Harry Potter entered the common room in 1998.
Unlike the other common rooms in the school, a logical riddle given by a bronze eagle-shaped knocker must be answered to enter. This could prove troublesome as anyone with enough intellect could intrude into the dormitory.
