Built in 1759 to house a dragoon garrison to fight the Camisards, the barracks were only used for a few years, as the troops were regrouped in Saint-Hippolyte-du-Fort.

In 1815, the "apporteurs de fourches", hackberry growers organized into a cooperative since 1698, acquired the barracks. The raw forks were shaped by fire. The cooperative produced 80,000 a year. Today, the Conservatoire de la Fourche produces a few hundred, mainly for decorative purposes. A few fork-trees are still grown on the banks of the Vidourle, while in the 1960s, every last vein of land was exploited. In addition to their vegetable gardens, each family owned a few vines, hackberry, cherry and olive trees. The dry-stone enclosures of these "pieces of land" can still be seen on the Mer des Rochers. To get there, the Chemin de Corconne has retained its large, calade-like steps.
