The Citadel of Belfort is a historically complex building, reflecting five centuries of fortifications. It was built after the conquest of the city in 1687, replacing a medieval castle that previously stood on this rocky outcrop.

impressive Vauban work , free access except for the museum

The opening times are published online and it's worth investing the €4 for entry. The complex is huge, although not all rooms are accessible. We visited without a guide, but were provided with detailed information material - in German! A very interesting complex that is maintained by a club. Respect!!!

This fort was built between 1875 and 1879. The fort forms the southern end of the defensive curtain of the Haute Moselle region, adjoining the fortified region of Belfort, which extends to the south. The fort was built as part of the French Séré de Rivières system of fortifications to defend France against a recurrence of the Prussian invasion of the Franco-Prussian War of 1870–1871. The fort was one of the most heavily armed forts in the northeast during the late 19th and early 20th centuries. Entrance 3€/pers. (free for accompanied children under 12). OPENING EVERY SUNDAY and public holidays from July 3 to September 18 (inclusive): from 2 p.m. to 6 p.m. (entrances close at 5:15 p.m.) Possibility of guided tour from April to October (Reservation required).

The fort of Giromagny, built between 1875 and 1879, is part of a line of defense called Haute-Moselle set up at the time. It was used during the First and Second World Wars, but remained abandoned for a long time. It was bought by the municipality in 1988. Since then, it has been restored and is open to visitors.

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. A testimony of this bunker built in 1885.
