Its deep passages have been flooded by the construction of a cooling water lake for a nearby nuclear power plant, but its surface features are being developed with an interpretive path through the surrounding forest.

[1] The site was surveyed by CORF (Commission d'Organisation des Régions Fortifiées), the Maginot Line's design and construction agency, in 1930.

[nb 1] Kobenbusch is a relatively compact gros ouvrage, with a short main gallery leading from the munitions and personnel entrances past to underground barracks to the combat blocks.

[18] There are no other casemates, observation points or shelters associated with Kobenbusch, although the petit ouvrage Oberheid is close at hand on the east.

[21] The Germans largely bypassed the area, advancing along the valley of the Meuse and Saar rivers, threatening the rear of the Thionville sector.

[23] While the entry and combat blocks remain visible, the underground galleries, barracks, ammunition magazine and utility areas, which lie at an average depth of 30 meters (98 ft) below the surface,[24] have been flooded by the cooling water lake of the nearby Cattenom Nuclear Power Plant.
