The Haute Moselle defenses form a link between the fortified encampments of Épinal and Belfort.

The fort overlooks the main roads to the northeast of Belfort, which form a crossroads at Giromagny.

An optical signal post permitted communication with the Fort du Salbert to the south.

[1] More substantial changes, including the proposed installation of a 75mm gun turret were not carried out, but a shelter or abri-caverne for 100 soldiers was excavated.

After the armistice the Germans used Giromagny to make propaganda films purporting to show the capture of a Maginot Line fortification using flamethrowers on a turret before blowing it up with dynamite.
