Romanesque architecture developed in Western Europe between the 10th and 12th centuries, combining elements of Roman and Byzantine architectural styles. It utilized stone, brick, and other materials from older Roman structures, and featured thick walls, rounded arches, and vaulted ceilings. Churches during this period often followed a Latin cross floor plan and included features like rose windows. Examples of prominent Romanesque buildings include Pisa Cathedral and its leaning bell tower in Italy as well as Notre Dame du Port and Angouleme Cathedral in France.
