A Saignon of the protohistoric period?

On La Gardette, regularly spaced piles of stones with comparable volumes (3 m3), are not collapsed huts of the Neolithic (-100 000 years), nor the ruins of a Saignon of the protohistory (-750 years). These hutches are the result of ancestral terroiring of the soil and have been piled up on sacrificed areas following the exhaustion of the soil. There is nothing extraordinary, then, that Neolithic tools, collected during stone removal, were found in hutches.
