Fort Haasdonk

Fort van Haasdonk in Beveren, East Flanders, was constructed between 1906 and 1914 as part of Belgium's National Redoubt defensive network protecting Antwerp from potential western attacks. The fortification remained inactive during World War I but was occupied by German forces after Antwerp's surrender. During World War II, the fort was extended with reinforced bunkers and equipped with anti-aircraft flak guns to defend against possible attacks from the Netherlands, and it served as a storage facility for V1-weapons. Today, one of the few remaining forts of the fortified position preserved in its original form, Fort Haasdonk has transitioned from military stronghold to natural habitat, providing sanctuary for a thriving colony of bats within its historic walls.
