Built from 1774 to 1779 by the architect Claude Nicolas Ledoux, the former royal saltworks of Arc-et-Senans constitutes a remarkable example of the French industrial heritage. Of Neoclassical style, this group of 11 buildings is today a UNESCO World Heritage Site. Visitors can look around the Guards' building, Director's building, blacksmith's workshop and cooperage. There is also a salt museum and the Claude Nicolas Ledoux museum.
