The simplest in a trio of great Cistercian abbeys (the other two are Silvacane and Notre-Dame de Sénanque), uninhabited Abbaye de Thoronet, 12km southwest of Lorgues, was built between 1160 and 1190. It’s remarkable for its ultra-austere architecture: pure proportions, perfectly dressed stone and the subtle fall of light and shadow are where its beauty lies.
