Citadelle de Dinant is a fortress rising dramatically above the Meuse River in Dinant, Namur, with origins dating to 1051 when prince-bishops of Liège first established a stronghold on this strategic site. The current fortress structure was built between 1818 and 1821 following the 1815 European settlement. Visitors can ascend 408 historic steps or take a modern cable car to experience the citadel's museums, interactive exhibits, and panoramic views of the Meuse Valley. The fortress features weapons and history museums alongside exhibits commemorating its significant role during World War I.
