Vault Structure


Left: Saint-Sernin, Toulouse
Right: Amiens Cathedral

Saint-Sernin, Toulouse: Barrel vaults with transverse arches over the central vessel. Quadrant vaults over galleries. Groin vaults over side aisles. Material is a local brick alternating with courses of limestone. Windows and portals are framed with limestone. Shafts and decorative details are cut limestone. The heavy ribbed vault of the Romanesque building are made possible by thick walls, heavy cruciform piers, and few windows.

Amiens Cathedral: Quadripartite ribbed vaults throughout. Star vault over crossing combining diagonal ribs, transverse ribs with liernes and tierceron. From prefabricated limestone (result of the use of drawings, division of labor, and the more economic structure of workshops). Ribbed vaults are structurally more efficient than a barrel vault that evenly distributes the weight and thrust along the wall. A ribbed vault directs thrust to specific points in the masonry--where the ribs meet the wall at the clerestory level. These in turn are supported by the use of flying buttresses visible on the outside of the building.
