Fort de Tancrémont, Military fortification in Theux, Belgium.
The fortified complex includes a central structure with gun turrets, observation posts, and a surrounding eight-meter-wide defensive ditch spanning two kilometers of tunnels.
Constructed in 1935 as part of the Fortified Position of Liège, the fort remained active until May 29, 1940, when it surrendered to German forces.
The descendants of the original garrison maintain the fort through the Amicale du Fort de Tancrémont organization, preserving its military heritage.
Visitors need warm, waterproof clothing and flashlights to explore the underground tunnels, which maintain cold temperatures throughout the year.
The fort extends 30 meters underground into slate rock, containing complete facilities including a hospital, kitchen, dormitories, and command centers.
