Belfort

Belfort occupies the Belfort Gap, a natural passage between the Vosges and Jura that links the Rhine and Rhône worlds. The site lies on the Savoureuse, about sixteen kilometres south of the Ballon d’Alsace, and its strategic corridor attracted human settlement since Roman times while exposing the town to repeated invasion. Gallo-Roman occupation was followed by Germanic settlement, especially by the Burgundians. By the thirteenth century, Belfort belonged to the counts of Montbéliard, who granted it a charter in 1307.

Austrian rule ended when the Treaty of Westphalia transferred the town to France in 1648. Louis XIV’s military architect Vauban extended its fortifications, turning the gap into a fortified gateway; a distinctive pentagonal citadel survives from that system.

Belfort’s history follows the double logic of a crossroads that invites movement and a fortress built to control it.
