Fort du Mont Bart is located to the south of Montbéliard France. It was built between November 1874 and July 1877 as part of the Séré de Rivières system of fortifications. The fort overlooks the valleys of the Doubs and the Allan at an elevation of 497 metres (1631 ft) standing to the south and rear of the fortified region of Belfort and in control of the road to Besançon. The fort was intended to augment the Belfort fortifications and to prevent an enemy from bypassing them.
