Fort de Koenigsmacker, German-built fortification in Thionville, France
The fortification consists of a central armored battery with four 100mm gun turrets connected by an underground network of tunnels and barracks.
Construction occurred between 1908 and 1914 as part of the Moselstellung defense system, following German annexation of Moselle after the Franco-Prussian War.
The fort represents early 20th-century German military engineering principles, incorporating dispersed structures rather than traditional continuous fortification designs.
The fort remains closed to visitors due to safety concerns, though plans exist to develop access paths and parking areas similar to Fort d'Illange.
The fortress housed 1,180 soldiers and featured central heating, an independent power plant, and ventilation systems considered advanced for its time.
