The calcareous rock formations have favored the creation of the numerous caves found along this route. Many relics that were found during archeological digs and are now on display at the Cuneo Municipal Museum (Museo Civico) prove that the caves, whose mouths at the bottoms of cliff faces enjoy excellent exposure to the sun, were already frequented in the Neolithic Era, between 4,800 and 3,500 B.C., by people of the square-mouthed vase culture. More recently, they were used as shelters by local shepherds.
