Duisburg.

Duisburg, located in North Rhine-Westphalia, is Germany's industrial heart with Europe's largest inland port connecting the Rhine and Ruhr rivers. Once a coal and steel powerhouse, the city has transformed abandoned industrial sites into cultural venues, parks, and museums. The Landschaftspark Duisburg-Nord offers a unique experience exploring a former ironworks, while the modern Innenhafen waterfront district features restaurants, museums, and architecture. Beyond the industrial heritage, the city provides access to the Rhine riverside, historic neighborhoods, and excellent camper van facilities for exploring the region.
