This ring fort was intended to cover the upper Marne valley, the Nancy and Belfort roads and the Paris-Basel railway line. It is the only Langrois fort of this generation to have retained its bastioned layout (designed before 1866). It appears to be fairly complex, as the cavalryman, forming a high, long-range fire ridge, consists of a reduction housing the barracks and storage warehouses. This reduction is separated from the four bastions forming the envelope by a second ditch on the front and side faces. Its distinctive feature is the presence of double wet ditches surrounded by ramparts. One of the 2 forts, along with the Bonnelle fort, to have opened fire on the Prussians.
