Dinant is positioned in the Upper Meuse valley at a point where the river cuts deeply into the western Condroz plateau. Sited in a steep sided valley between the rock face and the river, the original settlement had little space to grow away from the river, and it therefore grew, into a long thin town on a north-south axis along the river shore. During the 19th century the former Īle des Batteurs (Drummers' Island) to the south was attached directly to the town when a branch of the river was filled in.
Dinant has been enriched by the agricultural opportunities presented by the fertile of the land on the plateau that overlooks it. Within the town, brassware production is a traditional craft that has benefited from the presence of the broad and, at this point, easily navigable river which has provided for easy delivery of the raw materials and ready distribution of the resulting products emerging from the artisans' workshops. Another traditional source of wealth is provided by the limestone cliffs overlooking the town, which supported a high-end quarrying industry, producing black marble and bluestone, with the proximity of a relatively wide and deep navigable river facilitating distribution.
