Fort de Hollogne, Military fort and museum in Grâce-Hollogne, Belgium
Fort de Hollogne is a triangular military fortification in Grâce-Hollogne with thick walls and a surrounding defensive ditch. The structure was built entirely from concrete and served as a defensive stronghold against outside attacks.
The facility was built between 1881 and 1884 following a Belgian engineer's plans as a modern defense solution against neighboring states. During World War I, it resisted German forces for several days before being surrendered in 1914.
The fort represents how Belgium approached border defense and reflects late 19th-century military thinking about protection. It stands as a concrete structure when other nations still relied on traditional building methods.
You can tour the fort and see its interior spaces and concrete construction up close. Wear sturdy shoes since the paths are uneven and there are stairs to navigate.
The building was converted into a medical facility during World War II to care for wounded soldiers. This unexpected role shows how military structures were repurposed for entirely different uses.
