Norman architecture is a regional adaptation of Romanesque architecture. It originated in Normandy in northwest France. The style reached its highest development in England during the late 1000’s, after the Norman Conquest of 1066, and in the 1100’s.
Norman architecture is noted for its massive character, development of the six-part vault ceiling, and the use of Celtic and Carolingian patterns of carved ornamentation. Examples of Norman architecture include the churches of St. Étienne and La Trinité in Caen, France, and Ely and Durham cathedrals in England.
