The Limargue is encompassed by the dry stony plateaux of the Causse de Gramat and the verdant Ségala.
It is a narrow strip of land, rarely more than 10km wide, which has a particular force of attraction.
During the Jurassic period the sediments carried in the water were deposited in the different soil types, limestone, marl, clay and sandstone.
It is a fertile area of land, balancing on the edge of the dry plateaux of the Causses and the poplar and walnut groves of the Ségala.
Many prosperous medieval villages found their place amongst the neat fields, the gentle slopes and welcoming valleys.
All the underground rivers of the Quercy seem to find their way here.
