A fortress perched 100 metres above Dinant on the limestone cliff overlooking the Meuse. The current structure is largely Dutch — built between 1815 and 1821 by occupying troops — but the site has been fortified for over a thousand years, and the views are spectacular: the entire town stretched along the river with the bulbous spire of the Notre-Dame Collegiate Church directly below.
Inside the citadel, several rooms house military exhibits including a reconstructed 1914 trench memorial to the 674 Dinant civilians massacred by German troops at the start of the First World War. A small museum covers Dinant's long history of sieges. Reach the top by cable car from beside the church or climb the 408 stone steps. The cable car ticket includes citadel entry.
