To understand the landscape of the area the Cause must be explained, which put simply, is a high limestone plateau, with steep slopes.
In the case of Cahors, this plateau rises from 250 to 350 metres above sea level. For the Vignobles Saint-Didier Parnac, the highest point is the Priory of Cénac, which is near 300 metres. As for the slopes to Cahors, the gradient can be an impressive 20 to 30%, this is also seen at the Priory and the Chateau de Grézels.
In the case of Cahors, the bedrock of the plateau dates from the Jurassic period, which is 150 million years old made up of marine formation, unlike the valley, which comes from a fluvial formation.
