Thoronet Abbey (French: L'abbaye du Thoronet) is a former Cistercian abbey built in the late twelfth and early thirteenth century, now restored as a museum. It is sited between the towns of Draguignan and Brignoles in the Var Department of Provence, in southeast France. It is one of the three Cistercian abbeys in Provence, along with the Sénanque Abbey and Silvacane, that together are known as "the Three Sisters of Provence."
Thoronet Abbey is one of the best examples of the spirit of the Cistercian order. Even the acoustics of the church imposed a certain discipline upon the monks; because of the stone walls, which created a long echo, the monks were forced to sing slowly and perfectly together.
