Clos du Doubs (Franc-Comtois: Chôs di Doubs) is a municipality in the district of Porrentruy in the canton of Jura in Switzerland. It was founded on January 1, 2009 by the former municipalities of Epauvillers, Epiquerez, Montenol, Montmelon, Ocourt, Saint-Ursanne and Seleute. Soubey voted not to join the merger. Clos du Doubs can also refer to a range of the Jura folds south-west of Saint-Ursanne. The new municipality took its name from this regional designation (which also includes Soubey). ... Wikipedia
