The Jean Natte canal, some 9.5 km long, was built in the 15th century to supply water to flour mills.
Diverting the waters of the Gapeau from the Castille to the town center, where it passes underground, it emerges above ground to the end of the Parc du Béal and then flows underground again towards Hyères. It was also used for crop irrigation and, until the 1960s, as a washhouse.
Today, the béal is still used to water the surrounding crops and gardens. It is managed by the Association Intercommunale Libre des Arrosants du Canal Jean Natte.
