The Citadel of Namur is a fortress in the Walloon capital city of Namur, at the confluence of the Sambre and Meuse rivers. It is originally from the Roman era, but has been rebuilt several times. Its current form was designed by Menno van Coehoorn, and improved upon by Vauban after the siege of 1692. It has been classified as a Wallonia Major Heritage site. Its highest point sits at 190 metres (620 ft). Together with those at Dinant, Huy and Liège, the Citadel of Namur forms part of the so-called Meuse Citadels.
