The village lies at the confluence of the riversSagne andCélé, at the foot of the Rochecourbe cliffs. The village also forms part of thepilgrimage route for those travelling toSantiago de Compostella and is the final stop beforeCahors.
The overhanging cliffs that dominate the town are home to a ruined castle, built by the English and also known as thechâteau du diable ("devil's castle"). The castle was first mentioned in a document dating from 1259, and was the medieval home of the lords ofBarsac. In 1380, during theHundred Years' War, it fell into the hands of a force fromAquitaine controlled by the English. It was liberated ten years later by Jean d'Hébrard, lord of Saint-Sulpice, who subsequently ordered its demolition.
