The 18th century brought architectural renewal to Lausanne. A small group of local architects, including De Crousaz, Fraisse and Delagrange, were responsible for reconstructing public infrastructure. Following the ideal of a return to nature, the aristocracy built numerous “campagnes” near the city. “Campagne” was a local name for a country estate featuring a mansion and surrounded by parkland. Today these buildings are part of the urban fabric.
