In England, Norman nobles and bishops had influence before the Norman Conquest of 1066, and Norman influences affected late Anglo-Saxon architecture. Edward the Confessor was brought up in Normandy and in 1042 brought masons to work on the first Romanesque building in England, Westminster Abbey. In 1051 he brought in Norman knights who built "motte" castles as a defence against the Welsh. Following the invasion, Normans rapidly constructed motte-and-bailey castles along with churches, abbeys, and more elaborate fortifications such as Norman stone keeps.
