====Barrel vault====
The simplest type of vaulted roof is the [[barrel vault]] in which a single arched surface extends from wall to wall, the length of the space to be vaulted, for example, the nave of a church. An important example, which retains medieval paintings, is the vault of [[Abbey Church of Saint-Savin-sur-Gartempe|Saint-Savin-sur-Gartempe]], France, of the early 12th century. However, the barrel vault generally required the support of solid walls, or walls in which the windows were very small.<ref name=Toman/>
