The fort was one of the first built according to the fortification system developed by Lieutenant Colonel Raymond Adolphe Séré de Rivières.
Metz then became a crucial strongpoint on Germany's frontier, receiving sustained attention to its defenses that culminated in the Moselstellung of the early twentieth century.
[2] The pre-war French construction program comprised eight forts surrounding Metz at a distance of 3.5 - 5.5 km from the center of the city.
In their developed form, the Séré de Rivières forts of the 1870s were much simplified in plan, with less overt reference to historic prototypes.
[3] This was not considered a major disadvantage in the 1860s, when most opposing artillery was expected to be smooth-bored guns firing solid shot or gunpowder-filled shells on a low trajectory, with the aim of battering the walls of the fort so that breaches could be exploited by infantry.
At the same time, fuses were developed that enabled shells fired at a high angle from howitzers or mortars to explode in the air above an open position, making exposed fixed-position artillery untenable.
[1] Immediate German construction focused on dispersing gun batteries to flanking positions and reinforcing protection for personnel and ammunition against shellfire.
It was not a concentration camp, but an interrogation center for captured or arrested members of the Resistance, commanded by Schutzstaffel Hauptscharführer Georg Friedrich Hempen (* 27.07.1905).
