Durham Castle is an eleventh century building and the former home of the Bishops of Durham.

Originally commissioned by William the Conqueror in 1072, Durham Castle was intended to ensure Norman control in the North of England. Once under Church control, each bishop, on his appointment, would put his own stamp on the castle, and duly altered it to reflect his own glory.

However, despite the many changes, Durham Castle retains the layout of a Norman motte and bailey castle. It has a well preserved Norman chapel, dating from 1080, and many other features of interest.

Durham Castle is now a residential college for the University of Durham, but is open to visitors on guided tours.
