Oxford Castle and Prison is a historic complex dating back to the 11th century, located in the heart of Oxford, United Kingdom. It was originally built for military purposes by William the Conqueror in 1071, but throughout its history, it has served various roles, from a fortress to a prison, and now as a museum and heritage attraction. The castle features the medieval remains of St. George's Tower, the mound or motte, and a well chamber, alongside the 18th-century Debtors’ Tower and the Prison D-Wing. Visitors to Oxford Castle and Prison can explore its rich history through guided tours and interactive exhibits. The tours are led by costumed guides, and visitors have the chance to climb the Saxon St George's Tower, descend into the crypt, and explore the cells of the prison that has housed inmates for centuries. The site also offers stunning panoramic views of the historic city of Oxford from its tower.
