Division of the Romanesque style, originated by the Normans and introduced into England by William the Conqueror.
To a limited extent the Normans retained the general style of the French churches, and borrowed from the early Gothic.
The early period of Norman architecture is characterized by massiveness; the pillars were generally low and broad, the arches heavy and round.
Towers were extensively developed, and carving and sculpture were used.
Semi-circular arches distinguish Norman from Gothic and other styles of architecture.
Examples of Norman architecture are Canterbury Cathedral, and the great churches of Lincoln, Durham, Winchester, Gloucester, and Saint Paul's in London.
