A UNESCO World Heritage Site since 1982, the Royal Saltworks at Arc et Senans is the masterpiece of Claude Nicolas Ledoux (1736-1806), one of the Age of Enlightenment's most visionary architects. The site is also a rare example of early industrial architecture based on a utopian plan. 

Discover a place dedicated to Salt History ( from production to consumption), the Ledoux Museum, with its sixty models, is the only museum in Europe dedicated to an architect.

Our yearly themes gather from May to October : exhibitions, festival of music and  a garden festival designed and created by educational institutions in the eastern part of France and Switzerland.

Visitors can explore the site on their own, or join a guided tour or use an audio-guide.
