Hollowed out stones

These are rocks or stones where small concave holes in the shape of a cup have been carved with either hard stones or metal awls. These prehistoric findings date back to the Late Bronze and Iron Ages. It is still unclear what these carvings were used for: some experts believe that the hollowed out stones were used for religious and propitiatory rites. In the Hône area, the hollowed out stones are located in Montoulin (900m) and in Plan Priod (465m).
