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.
