Haute-Provence National Geological Reserve

Guardian of our treasures

The largest protected geological reserve in Europe, the Réserve nationale Géologique de Haute-Provence stretches between the Alpes-de-Haute-Provence and Var departments. It covers 230,000 hectares, including part of the Verdon. A veritable open-air museum with signposted discovery trails, this vast protected area is home to an impressive fossil heritage.

The ammonite

The ammonite, a fossil of legends

The shape of ammonites has fascinated people on every continent for centuries. From Germany to Great Britain, via Nepal, they have inspired numerous myths and legends. They take their name from Ammon, one of the most important gods of ancient Egypt. In Barrême, they’re everywhere, and that’s no legend. The village gave its name to the geological period in which these molluscs lived, over 110 million years ago: The Barrêmien. Come through the doors of the town hall to discover them.

The outcrop used to define the Barrêmien geological stage is located on the route d’Angles.

The Siren Valley

exceptional geo-site

Head for Castellane, and what was meant to be a simple hike becomes a journey between science and mythology. First you’ll follow the Sirenian Trail to discover the deposit of bones of these ancestors of dugongs and manatees. Afterwards, visit the Maison Nature et Patrimoines to find out all about the Sirenians who grazed here 40 million years ago. And how, despite their far-from-beautiful looks, they are the origin of the siren myth.
