Located on the edge of the Dordogne and Charente departments, Argentina's limestone plateau is one of the major natural sites of the Périgord Limousin Regional Natural Park. Various elements enrich the course of historical and cultural interest: - the Romanesque church, which keeps the memory of its transformations since the 11th century; - the singular landscape linked to the geology and the Cretaceous period when, at the site of the land of Mareuil, a vast lagoon protected by a coral reef was laid out; - quarries that form a network of 50 hectares of galleries, where the inhabitants worked from an early age; - the ruins of the castle reminiscent of the legend of the beautiful Argentina. The signs of the course give you the secrets of the place! A free guide booklet is available at tourist offices or at the Périgord Limousin Regional Natural Park.
