The Zollverein colliery, also known as the "Eiffel Tower of the Ruhr area", was a hard coal mine in Essen that was active from 1851 to 1986. It developed into one of the largest in the Ruhr area and had the highest funding in 1888 - 1901, 1932, 1934 - 1938 and 1945. It was one of the few plants (shaft 1/2) with a double Malakoff tower. Until 1920 it was owned by the Franz Haniel Haniel family. The plant was very profitable from the start. Today it is an architectural and industrial monument. Together with the immediately adjacent Zollverein coking plant, shafts 12 and 1/2/8 of the colliery have been part of the UNESCO World Heritage since 2001.
As with almost all of my illustrations, I work from the background to the foreground.
It was drawn on an Apple iPad Pro 12.9 using Adobe Fresco and Kyle T. Webster's famous brushes.
Thank you for your attention!
