Ancient Diocese of Sarlat
The Abbey of Saint-Sauveur of Sarlat, later placed under the patronage of St. Sacerdos, Bishop of Limoges, seems to have existed before the reigns of Pepin the Short and Charlemagne who came there in pilgrimage. They were called its "founders" in a Bull of Pope Eugene III (1153).
