Bedford Castle was a large medieval castle in Bedford, England. Built after 1100 by Henry I, the castle played a prominent part in both the civil war of the Anarchy and the First Barons' War. The castle was significantly extended in stone, although the final plan of the castle remains uncertain. Henry III of England besieged the castle in 1224 following a disagreement with Falkes de Breauté; the siege lasted eight weeks and involved an army of as many as 2,700 soldiers with equipment drawn from across England. After the surrender of the castle, the king ordered its destruction.
