Fort d'Aubin-Neufchâteau

Fort d'Aubin-Neufchâteau is a military fortification in Dalhem arranged in a triangular layout with multiple combat blocks, artillery positions, and underground galleries running throughout the structure. The fortification displays typical features of early 20th-century defensive engineering with sturdy concrete construction.

The structure was built in the 1930s as part of the Fortified Position of Liège and designed as a defense line against potential aggression. It was surrendered on May 21, 1940, after ammunition ran out and the garrison could no longer resist the German forces.

The fort is experienced by visitors as a place where Belgian engineers demonstrated their mastery of fortification design, with preserved weapons and documents that show this craftsmanship. The rooms speak of a time when the country was preparing to defend itself against possible threats.

Visitors can join guided tours to explore both the surface fortifications and the underground passages while learning how this defensive facility operated. It is wise to wear suitable footwear since some areas can be damp and uneven.

The site now provides a refuge for bat populations that use the underground chambers as ideal habitats. This unexpected function shows how a military location has become a sanctuary for wildlife.
