Saline royale

The Royal Salt works of Arc-et-Senans is an 18th century factory that was designed by Claude-Nicolas Ledoux. The plant, which was created to produce salt, which at the time was of fundamental economic importance, has been classified as a UNESCO World Heritage site. With its unusual operation methods and exceptional architecture, the Salt works are also the result of the architect's philosophical reflection as he attempted to design the ideal workers' city.
