Oxford Castle and Prison 
Description
The first major part of the castle was built by William the Conqueror in the 1070's and the site has been occupied ever since. For most of it's life it was a prison, only finally relinquishing that roll in 1996 when it was closed down as it was too expensive to fit toilets into the cells to end slopping out. Today the bulk of the prison has been converted into a hotel, but one wing of the prison, along with the oldest tower of the castle are open to the public which you can visit on a character guided tour.
