Oxford Castle Castle

Oxford Castle is a Norman-era castle and former prison in central Oxford, England, founded by Robert D’Oyly around 1071. It forms one of the oldest historic complexes in the city and retains a prominent motte and a surviving medieval tower.

The site presents the castle mound and stone tower as the main visitor highlights, with guided tours that cover the medieval fortifications and the complex’s later use as a gaol. Interpretive displays and tours typically explain the sequence from motte-and-bailey earthwork to stone castle and then to prison, and visitors can climb the tower for views over the city.

Construction began in the late 11th century under Norman authority as a motte-and-bailey; stone buildings and defensive works were added in subsequent medieval centuries. The complex was adapted and used as a county prison for many centuries before that use ended in the late 20th century.

The castle stands in central Oxford, within the historic core of the city and a short walk from Oxford’s main shopping streets and transport links. It lies on the north side of the city centre close to the River Thames and existing medieval street pattern.

• Prison history: The site operated as a county gaol for several centuries and the prison was finally closed to inmates in 1996.
• Visitor access: Guided tours typically include access to the mound and tower and explain both the medieval fortifications and the later prison buildings.

What to See#

• Castle Mound (motte): The motte formed from the original Norman earthwork, surviving as a raised mound at the heart of the site and providing views over the surrounding city center.
• St George’s Tower: A surviving medieval stone tower that rises above the castle complex and is accessible to visitors on guided climbs; it dates from the Norman/medieval phase of construction.

Oxford Castle is located in Oxford city centre and is a short walk from Oxford railway station (about 15-20 minutes) or easily reached by local bus services. The castle sits close to the Radcliffe area and the Covered Market.

• Book guided tours of the underground prison and keep an eye out for interactive exhibits - they offer the best historical context.
