History of the Saline Royale (Royal Saltworks) at Arc-et-Senans
This masterpiece by architect Claude-Nicolas Ledoux was built during the reign of Louis XV between 1775 and 1779 and was the first great achievement of industrial architecture.
The Saline Royale was a purpose-built factory where almost all the workers lived on-site. It comprised a semi-circle of 11 buildings, five of which housed workshops and worker accommodation. It was one of the largest saltworks in Europe at the time and was operated in association with the one at Salins les Bains by means of two 21km-long pipelines which brought the brine from Salins. Rendered obsolete by new techniques, the Saline Royale closed down in 1895.
