The coking plant’s core focus was on the production of coke. Here, you differentiate between two production areas – the so-called black side and the white one. The black side takes its name from the dark dust that collected in this area. That’s because that is where the coke oven batteries previously ran at full speed, where coke was produced. The white side is where plants were located for the extraction of carbon recyclable materials and the preparation of coking gases. After 64 years of operating time, the shutdown took place on December 15, 1992. Since 1995, Hansa coking plant belongs to the Foundation for the Preservation of Industrial Monuments, thanks to which the plant with a size of 10.7 ha was protected against demolition.
A fascinating sight over the Hansa coking plant’s site awaits visitors today. High towers stretch up towards the sky. Gigantic machines everywhere, steel dinosaurs of the industrial era. And right in the middle of this, nature seems to be coming to life again.
Since 1998, the coking plant has been entered in the list of monuments of the City of Dortmund. And on the plant’s birth certificate is the name Hellmuth von Stegmann und Stein (1892 – 1929). As construction director of Vereinigte Stahlwerke AG, the architect is considered as the father of Hansa coking plant. Von Stegmann und Stein clearly organized the plant’s buildings according to the production processes and followed a factual-functional architectural style. A style that casts a spell over countless visitors right up until today.
