The Neolithic

Chauvé is one of the villages in the Pays de Retz with the most menhirs. These sandstone megaliths, erected around 3,500 BC, bear witness to human occupation of the area during the Neolithic period.

This sandstone boulder can be seen in a cultivated field as you approach Saint-Père-en-Retz.
This elongated stone is quite large. It is 5.80 m long, 3.30 m wide and 1.80 m thick.

Although it is not possible to access it directly, as it is located in a private property, it is possible to make out on the stone :


on the top and the periphery, cupules (depressions dug into the stone),
on the edge of the upper part, an artificial basin approximately 30 cm in diameter.
