The Mediterranean climate has favored the cultivation of the olive tree on the town territory. The water resources of the Roya river and some valleys have allowed the installation of water mills on the one hand to grind the olives (oil), and on the other hand to grind the grains (flour).
The impeller powered by channeled water was driving the mechanics of the different machines.
The vertical wheels turned in the “tracks”, vats in which the olives were poured to grind. The press where the “scourtins” (circular bags made of braided fiber) were stacked filled with the olive pulp was driven by the same energy.
Some mills had a flour room equipped with millstones and sieves.
A Coupéra mill, located in the north of the village, includes two rooms equipped for oil and for flour. It has been converted into a museum.
