Fort Tancrémont is a significant military historical site located near Pepinster, forming part of the Fortified Position of Liège. It was constructed between 1932 and 1936 as one of the four new forts designed to bolster the Belgian border against a potential German invasion. Although smaller in scale compared to the famous Eben-Emael, it played a heroic role during World War II. Under the command of Captain Abel Devos, the garrison resisted fiercely and only surrendered on May 29, 1940, one day after the official capitulation of the Belgian army. The fortification features an extensive network of underground tunnels situated 28 meters below the surface, connecting various combat blocks. Today, the fort serves as a museum, documenting the technical sophistication of interwar defensive works and the daily lives of soldiers during the siege.

Touring Fort Tancrémont pairs perfectly with a visit to the nearby Fort d'Aubin-Neufchâteau or the immense Fort d'Eben-Emael for those doing a themed bunker route. The appealing town of Spa is also just a short drive away, offering excellent dining and relaxation options after a damp fortress tour.

💡

Insider tip

Make sure to use the restroom facilities before descending into the fortress, as amenities deep underground are virtually non-existent. A small flashlight can also be incredibly useful for illuminating darker corners that standard gallery lighting might miss.
