Listed as a UNESCO World Heritage Site since 1982, the Saline Royale d'Arc et Senans is the masterpiece of Claude Nicolas Ledoux (1736-1806), a visionary architect of the Age of Enlightenment. It is also a rare testimony to the history of industrial architecture. A salt factory, the Saline Royale was created by Louis XV and built between 1775 and 1779.

The Saline Royale functioned as an integrated factory, housing almost the entire working community. Built in the shape of an arc of a circle, it housed both production and living quarters - 11 buildings in all. Rendered obsolete by the advent of new technologies, the Saline Royale closed its doors in 1895. Abandoned, looted and damaged by fire in 1918, the Département du Doubs acquired the property in 1927, saving it from ruin.

Three successive restoration campaigns, completed in 1996, restored it to its former glory.
