Tour guide Manuela Sass at the tapping point of Blast Furnace No. 5. It was the last and most modern blast furnace at the Thyssen steelworks in Meiderich. It came into operation in 1973 and produced special pig iron from ore at temperatures of up to 2,000 °C – as a feedstock for Thyssen’s steelworks. It was the last to be shut down on 4 April 1985, after only 12 years, due to crises in the steel market. Manuela Sass as a tour guide at Landschaftspark Duisburg-Nord (Duisburg-Nord Landscape Park).
