Deddington Castle

About

Deddington Castle is an extensive earthwork in the village of Deddington, Oxfordshire, all that remains of an 11th-century motte-and-bailey castle, with only the earth ramparts and mound now visible. The castle was built on a wealthy former Anglo-Saxon estate by Bishop Odo of Bayeux, half-brother of William the Conqueror. It was strengthened in the 12th century, with some stone defences added, but from the 13th century onwards it fell into disrepair, and the stone buildings were eventually dismantled and sold.

The castle played a minor part in the English Civil War, but after Deddington's strategic importance waned, the site lay vacant for many decades, used only for grazing and forestry. In the 19th century the site was used for recreation and sports, until it was sold to the parish council in 1947. It now serves as a park and nature walk.

The site is protected under UK law as a scheduled monument.
