Wallingford Castle

Wallingford Castle stands beside the River Thames in the old market town of Wallingford, Oxfordshire. Built in the 11th century as a motte-and-bailey fortress on the site of an earlier Anglo-Saxon burgh, it became one of the strongest royal castles of the 12th and 13th centuries. The historian Nicholas Brooks called it “one of the most powerful royal castles of the 12th and 13th centuries.” The castle survived repeated sieges during the Anarchy and never fell to attackers. Later it served as a luxurious residence for royalty, including King John and the 1st Earl of Cornwall. After Henry VIII abandoned it, the castle declined and was slighted during the Civil War. The castle’s long history includes dramatic episodes from the civil wars of Stephen and Matilda. Brien FitzCount, son of the Duke of Brittany, strengthened the stone defences in the 1130s and built a shell keep and curtain wall. During the siege of 1152 Stephen built counter-castles at Crowmarsh Gifford and near the bridge, yet failed to take the fortress. The Treaty of Wallingford, negotiated on the meadows outside, ended the conflict and secured Henry II’s path to the throne. King John later used the castle during the First Barons’ War, reinforcing its walls and garrison. Today visitors walk among the remaining stone walls and earthworks. The great motte rises beside the Thames, its base still showing traces of the original ramparts. The shell keep and curtain wall mark the heart of the medieval stronghold. Nearby, earthworks from the Civil War sieges remain visible. The riverside setting offers quiet views over the water meadows where Stephen and Henry once faced each other. The site remains open and largely undeveloped, letting the castle’s past speak for itself.
