Hogwarts houses: Ravenclaw

Ravenclaw is one of the four houses at Hogwarts School of Witchcraft and Wizardry and it was born under Rowena Ravenclaw, from whom it gets the name. The house especially values intelligence. Its symbol (animal) is the eagle and its colours are blue and bronze. The Grey Lady is the house ghost and when she was alive she was Helena Ravenclaw, daughter of Rowena Ravenclaw.
The Ravenclaw Common Room (the place where the Ravenclaw students spend their time and do their homework) is in Ravenclaw Tower, on the west side of the Castle. At the door the students must answer a riddle that the eagle-shaped door knocker asks them.
The head (ruler) of Ravenclaw house is Filius Flitwick.
