11 Forgotten Industrial Ruins That Are Now Unique Art Installations

4. Landschaftspark Duisburg-Nord, Germany: Blast Furnace Illumination

This decommissioned ironworks wasn't demolished; it was reborn as a public park where industrial ruins become sculptural elements. The most striking feature is the nightly light installation by Jonathan Park. Blast furnaces, ore bunkers, and smokestacks are bathed in vibrant, shifting colours – reds, blues, greens – transforming the brutal structures into ethereal objects against the night sky. It's ingenious because the light doesn't hide the rust and decay; it celebrates the forms, turning symbols of heavy industry into points of unexpected nocturnal beauty and public enjoyment.
