The construction of the Mont-Vaudois fort took 3 years between 1874 and 1877. In 1885, the invention of the torpedo shell, I suppose, bombarded the fort from above and led to the construction of an underground bunker as a defense. In 1944, faced with the advance of the Allies, a German unit occupied the fort and was driven out without success, despite a barrage of 3,000 shells. The Germans withdrew on their own.

Former German principality, and nicknamed the city of princes, the country of Montbéliard draws its identity from its Protestant culture and its original history on French soil. It is known to be the cradle of Peugeot automobiles, but it also owes its success to its famous Montbéliarde breed of cows that can be seen everywhere in the Jura and the Doubs, which provides the milk for the production of Comté. Along with Strasbourg, it has one of the most beautiful Christmas markets in the whole country. The old center is interesting and worth a visit.
