Discover the traces of a giant animal that has been extinct for millions of years, but whose footsteps have been preserved in the Causse ground: a dinosaur...

This limestone hillock overlooking the Tarnon valley was submerged in a vast lagoon at the edge of the Grands Causses sea... That was 200 million years ago, at the beginning of the age of the dinosaurs, and one of them was walking along the bank on its hind legs. While the district of Saint Laurent has yielded up various pieces of evidence of pre-historical human occupation, excavations carried out on the Castellas site definitively allow us to date the first settlement on this limestone plateau to the Upper Neolithic (3000 – 2500 BC). It took the form of a cap barré fortified site.
