In 2009, UNESCO recognized the exceptional and universal value of the Grande Saline.
Since its classification as a World Heritage Site, the number of visitors has doubled (approximately 70,000 per year). They come to immerse themselves in the history of this town, Salins, which has taken advantage of an incredible gift of nature: salt.
Its manufacture by man, from sources of salt water and a principle of evaporation of brine by fire, has been practiced on this site for about 7,000 years and, in the Middle Ages, it occupied no less than 800 people (salt workers, coopers, blacksmiths, lumberjacks ...).
Its production alone contributed to half of the income of Franche-Comté region!
