Fort de Flémalle

Fort de Flémalle is a military fortress near Liège with a four-sided structure surrounded by an eight-meter-wide ditch. The building has multiple artillery positions integrated into its central defensive area and was built from reinforced concrete.

The fortress was built in 1888 under the direction of Henri Alexis Brialmont as part of a series of defenses around Liège. It withstood German attacks until August 16, 1914, when it became the last fortress of the city to surrender.

The fort holds collections of military equipment and Belgian uniforms that show how defensive techniques changed over the decades. Visitors can see these objects today and understand what role the fort played in people's lives during wartime.

Visitors can explore the underground passages and artillery positions on guided tours offered on the third Sunday of each month. It is best to arrive early and wear sturdy shoes, as the paths on the grounds can be uneven.

The fort has virtual reality stations that show visitors how certain locations looked during World War II. These digital reconstructions allow people to experience the past in a direct way.
