Oxford Castle Prison

Oxford Castle Prison is a partly ruined Norman castle and former prison on the western side of central Oxford. A guided tour takes you through surviving parts of the site, including prison cells and the ancient crypt, with costumed guides telling stories from its long history. Climb St George’s Tower for views across the city, then use the free time after the tour to revisit the exhibition areas. The tower climb involves more than 100 steps, so it may not suit everyone.

A Norman castle above the city

Oxford Castle was built between 1071 and 1073 by the Norman baron Robert D’Oyly the elder. The castle stood over the western side of the town, within the line of the Saxon walls. It began as a wooden motte-and-bailey castle, a design built around a raised mound and enclosed courtyard. Much of the structure was later rebuilt in stone, around the late 12th or early 13th century.

The castle’s remains include the mound and St George’s Tower, among Oxford’s oldest surviving buildings. The site is partly ruined, so the visit is a chance to understand its earlier form as well as see the surviving structures. Its history is tied to more than military defence: it was also a royal fortress and a centre of justice.

The castle during the Anarchy

During the civil war between Stephen and Matilda, known as the Anarchy, Oxford Castle was caught up in the struggle. One story tells of Matilda escaping a siege in winter. With snow on the ground and rivers frozen, she and a group of knights are said to have slipped away in a storm, using white clothing to blend into the landscape.

The castle’s military role declined over time. After much of it was damaged during the English Civil War, the remaining buildings continued to serve as Oxford’s prison. The prison closed in 1996, bringing that part of the site’s history to an end.
