Royal Saltworks
Arc-et-Senans, France
Claude-Nicolas Ledoux’s semicircular 18th-century saltworks, designed as an ideal factory town. A UNESCO site, with a large garden festival in summer.
The Royal Saltworks at Arc-et-Senans was built from 1775 to designs by Claude-Nicolas Ledoux. The complex forms a semicircle: the director's house, topped by a belvedere, stands at the centre, the salt-boiling buildings flank it on either side, and a separate gatehouse forms the entrance. The brine arrived through a 21 km pipeline from Salins-les-Bains, and the fuel was wood from the Forest of Chaux. The planned "ideal city" was never begun. Salt production ended in 1895; UNESCO inscribed the saltworks as a World Heritage Site in 1982 and extended the listing to Salins-les-Bains in 2009.
Allow about two hours for a walk around the site. There are exhibitions and changing events, so check opening times and the programme on the saltworks' website before you go (as of October 2026).
