This church built between 1540 and 1550 has survived intact. The frieze on the outside depicts the exploits and titles of Galiot de Genouillac. Such decoration – sieges of towns and battles, horsemen, infantrymen and artillerymen – is unusual on a religious building and represents an irreplaceable record for military historians. The chapel vault with a sixteen-pointed star-shaped plan forms a dome supported by squinches, in a remarkable and extremely rare effect.
