Landschaftspark Duisburg-Nord

Landschaftspark Duisburg-Nord transforms a decommissioned 180-hectare ironworks in Duisburg-Meiderich into one of Europe's most distinctive urban parks, opened in 1994 as part of the International Building Exhibition Emscher Park. Rather than demolishing the blast furnaces, ore bunkers, and casting halls of the former Thyssen steelworks, planners repurposed them into a climbing park, scuba diving basin, open-air concert venue, and observation tower. Blast Furnace No. 5 can be climbed via steel stairways for sweeping views across the Ruhr region. After dark, a permanent light installation by designer Jonathan Park washes the furnace complex in shifting colors — a transformation that turns the deliberately preserved industrial ruins into something closer to a stage set. The Guardian ranks it among the ten best city parks in the world, alongside the New York High Line and London's Hampstead Heath.
