Diaphragm arches in Romanesque architecture (St Philibert, Tournus)

A diaphragm arch is a transverse wall-bearing arch forming a partial wall dividing a vault or a ceiling into compartments[1] while also bracing the walls.[2]

When used under a wooden roof (with solid spandrels) it has the advantage of providing a partial firebreak.[3] It was first used in Roman Syria, during the 2nd century AD.[4] The diaphragm arch is present in Islamic, Carolingian, Ottonian and Romanesque architecture.[2]
