The 16th-century water mill in Sainte-Nathalène on the edge of the small Enéa river still manufactures walnut, hazelnut and almond oils in the traditional way.
The wheel of the mill turns an old-fashioned grinding mechanism which crushes the nuts under a large stone and the resultant paste is heated before being pressed and filtered for its oil. There are tours throughout the year and a shop selling their produce.
