The Backelsberg, on whose summit Haus Hartenfels is located at a height of 82.52 m, is the highest natural elevation in Duisburg at 83.7 m. It is surrounded by dense beech forest, so there is no view possible.
Duisburg is still Europe's most important steel location - here you can see why: the view goes straight to ThyssenKrupp, but also to ArcelorMittal and - in the very south of Duisburg - to Krupp Mannesmann.
