Fort de Tancrémont

Theux, Belgium, Belgium

---

Fort de Tancrémont is a Belgian fortress located between the communes of Theux and Pépinster.

Built in the late 1930s and inaugurated in 1937-1938, it was the last of the newer forts designed to strengthen the Fortified Position of Liège before World War II. The fort features five combat blocks connected by underground galleries about 28 meters deep and is surrounded by a defended ditch.

During the German invasion of Belgium in May 1940, Tancrémont was notable for resisting surrender longer than most forts, finally capitulating on May 29 after the general Belgian surrender. Its garrison was well-prepared despite construction still ongoing at the time of attack. Today, the fort is preserved as a museum that offers visitors a well-maintained glimpse into Belgium's military history, featuring original armaments, exhibits of wartime life, and guided tours through its extensive underground galleries.

The site also offers panoramic views of the surrounding countryside, making it a significant historical and cultural destination.
