Classified as a World Heritage site by UNESCO since 1982, the Royal Saltworks of Arc-et-Senans is the masterpiece of Claude Nicolas Ledoux (1736-1806), visionary architect of the Enlightenment. Its construction was begun in 1775 and the commissioning of the plant took place in 1779, under the reign of Louis XVI.
Innovative for its time, this is an outstanding example of the type of structurization of space that would be developed during the 19th century. Though Ledoux’s initial project was to realize the ideal city, this project would never be realized. Because there is no salt in Arc-et-Senans, it was transported from Salins-les-Bains to be treated here.
Today the Royal Saltworks of Arc-et- Senans is most famous for the architecture of its buildings for its innovative industrial activity.
