Located on private property and not part of the Geopark, you are asked to show the greatest respect for the site.

It is one of the last remaining plaster production sites, still in good condition.
The site combines the oven where the gypsum was heated and the mill (probably animal-powered) for grinding the plaster. In the areas of Provence with higher altitudes, gypsum is abundant in the earth. It is linked to the great geological-rifts that created distinct geological formations (for example, the Grand-Vallon and Vermeil fault-lines).

Used since Classical Antiquity Time, plaster is a relatively inexpensive material because it is heated at low temperature, and it is still used today for many different purposes.
