The Fort de Tancrémont is a Belgian fortification located about south of Pepinster. The fort was built in the 1930s as part of the fortified position of Liège, augmenting the twelve original forts built to defend Liège in the 1880s with four more forts closer to the Belgian frontier with Germany. The fort was the last Belgian fort to surrender to German forces in the opening days of World War II, following the dramatic assault on Tancrémont's sister fort, Fort Eben-Emael. Tancrémont has been preserved and may be visited by the public.
