Located in Saint-Hilaire-la-Forêt, 20 km south of Les Sables d'Olonne and close to the ocean, the Préhisto'site du CAIRN, a living, fun and educational museum, welcomes you to the land of megaliths!

As a family, you can explore the Neolithic habitat, participate in archaeological excavations, see the inside of a dolmen and learn about plants and recipes from our ancestors… A real return to basics!

The Vendée, very famous for its coastline, conceals many other riches that are often overlooked. In our territory, it is a unique heritage dating from prehistory: menhirs and dolmens. The mission of Préhisto'site is to discover these giants of sandstone or granite.

The park is made up of different thematic areas: a prehistoric garden; a menhir movement area; a hunting area with 3D animals; a reconstructed dolmen; a reconstructed Bronze Age house; a fishing area; a nomadic habitat space; “little stone giants”; a polisher and its jewelry manufacturing workshop; an art space and its charcoal drawing workshop.
