Worcester Castle was a Norman fortification built between 1068 and 1069 in Worcester, England by Urse d'Abetot on behalf of William the Conqueror. The castle had a motte-and-bailey design and was located on the south side of the old Anglo-Saxon city, cutting into the grounds of Worcester Cathedral. Royal castles were owned by the king and maintained on his behalf by an appointed constable. At Worcester that role was passed down through the local Beauchamp family on a hereditary basis, giving them permanent control of the castle and considerable power within the city. The castle played an important part in the wars of the 12th and early 13th century, including the Anarchy and the First Barons' War.
