Ravenclaw.

Ravenclaw was founded by Rowena Ravenclaw. Members of this house are characterized by their intelligence and cleverness. Its house colors are blue and bronze, and its symbol is the eagle. The house ghost, who in life was the daughter of the house’s founder Rowena Ravenclaw, is the Grey Lady. Many great wizards and witches have come from this house, including Filius Flitwick and Luna Lovegood.

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. Unlike the other common rooms in the school, a logical riddle given by a bronze eagle-shaped knocker must be answered to enter.
