The towns of La Chaux-de-Fonds and Le Locle, situated in the Jura mountains of the Canton of Neuchâtel, bear witness to the successful symbiosis between their urban setting and their watchmaking industry. After suffering devastating fires, their reconstruction in the early 19th century was carefully planned. The chequerboard design of the roads and constructions was specifically adapted to the requirements of the thriving industry. Many of the buildings displayed a well-thought-out combination of living quarters, production areas and offices. Today, they are a testimony to the history of local craftsmanship and industry. The fact that the region is still an important international watchmaking centre is proven by the many well-known watch brands which have their headquarters here.
