Fort d'Aubin-Neufchâteau, Military fortification and museum in Dalhem, Belgium.
Fort d'Aubin-Neufchâteau is a concrete military fortification in Dalhem, Belgium, built as part of the Fortified Position of Liège, with a triangular layout that includes several combat blocks, artillery positions, and a network of underground galleries. The structure has both surface-level elements and subterranean passages that together form a connected defensive system.
The fort was built in the 1930s as part of Belgium's defensive line around Liège, designed to protect the country from attack from the east. In May 1940, the garrison surrendered after a German special weapon made further resistance impossible.
The fort is open to visitors who want to walk through the interior of a Belgian 20th-century fortification and see how soldiers lived and worked in these conditions. Original equipment and documents are still displayed inside the combat blocks and underground corridors.
Guided tours allow visitors to explore both the surface fortifications and the underground passages while learning how the facility worked. Sturdy footwear is a good idea since some areas inside are damp and uneven.
The underground chambers of the fort are now home to bat colonies that use the dark, damp spaces as a winter habitat. These animals are now a regular presence in the site and can sometimes be spotted during tours.
