Wallingford Castle, Wallingford, Oxfordshire
This fragment of wall is all that is left of Wallingford Castle. The castle was begun in 1067 by order of William the Conqueror. A Motte and Bailey castle was complete by 1071. It was expanded in the 13th century under King John, and King Henry III. In 1335 Edward II gave the castle to his son Edward, the Black Prince, Duke of Cornwall. He spent lots on repairs and improvements. By the 1540s the castle had fallen into disrepair and stone was being used for other buildings in the town. During the Civil War it was fortified as a Royalist stronghold. Charles I inspected these new works in 1643. On the 17th November 1652 Cromwell's Council of State ordered its demolition.
