Museum Citadel of Dinant.  The place where the town of Dinant is located has always been a place of strategic importance; therefore it shouldn't be a surprise to know that on the spot of the current citadel, there already used to be a castle in the 11th century. In its present form, the citadel only dates back to 1821, when it was constructed by the Dutch. The citadel can be visited and hosts a museum inside. On top of that, you have a great panoramic view on the town and the  Meuse that are located at its feet [more information].
