Durham Castle - view from within the Castle courtyard

Durham Castle is a Norman castle in the city of Durham, England, which has been wholly occupied since 1840 by University College, Durham. It is open to the general public to visit, but only through guided tours, since it is in use as a working building and is home to over 100 students. The castle stands on top of a hill above the River Wear on Durham's peninsula, opposite Durham Cathedral (grid reference NZ274423).
