The castle was built in the 1071 by Robert D'Oyly to enable William the Conqueror to control the Upper Thames valley. It is thus one Oxford's very oldest buildings but most of the structures have gone leaving only the motte or mound itself (right) with a well-chamber inside, and St George's Tower behind which became incorporated into the County Gaol (it contained the condemned cell). Recent innovations have turned these forbidding remnants of the past into a recreational area.
