Fort d'Embourg, Military fortification and museum in Chaudfontaine, Belgium.

Fort d'Embourg is a fortified installation with rectangular shape, surrounded by a 20-foot (6 meter) deep ditch and concrete walls. The structure was built with gun positions designed to control and defend the Vesdre valley from above.

Fort d'Embourg was built between 1888 and 1892 to General Henri Alexis Brialmont's plans, one of twelve forts forming the Fortified Position of Liège. It was bombarded from 12 August 1914 and surrendered the next day after 48 hours of shelling. Upgraded in the 1930s, it fought again in May 1940, when its 75 mm turrets were knocked out before the garrison surrendered.

The fort displays weapons, uniforms, and personal items from soldiers across different military periods. Through these exhibits, visitors see how Belgian military forces prepared themselves over the decades.

The fort sits about 7 kilometers southeast of Liege and is open to visitors with guided tours explaining the architecture and defensive systems. Wear sturdy shoes, as there are many stairs and uneven surfaces inside.

This was one of the first Belgian military installations to use unreinforced concrete, representing a new building method for its time. The approach was experimental and marked a departure from the stone construction common in other defensive structures.
