musée Claude-Nicolas Ledoux d'Arc-et-Senans
The Musée Claude-Nicolas Ledoux d'Arc-et-Senans is a museum of architecture and urban planning of the royal saline of Arc-et-Senans (classified as a World Heritage Site), in the Doubs in Franche-Comté. Inaugurated in 1991, he is dedicated to the visionary utopian urbanist freemason architect Claude-Nicolas Ledoux (1736-1806). Nicknamed the architect of the Enlightenment, he was one of the main utopians and representatives of neo-classical architecture in the 18th century.
