Fort de Lantin stands in the town of Juprelle as a remarkable testament to 19th-century military engineering, built between 1886 and 1888 to protect the city of Liège. Uniquely, it remains the only fort in the Liège fortified position that has not been substantially modified since 1914, preserving its original state and offering visitors an authentic glimpse into late-Victorian military life. The triangular structure measures 200 meters at its base and was armed with multiple artillery turrets featuring 15cm, 21cm, 12cm, and 5.7cm cannons. During World War I, the fort surrendered on August 15, 1914, following Germany's invasion. Today, visitors can explore the preserved fort and its on-site museum displaying period artifacts, experiencing the daily world of soldiers who defended this critical Liège position.
