The renaturation of the Emscher, previously known as the dirtiest river in Germany, is an outstanding example of environmental restoration work. Through this initiative, the river has transformed from a former industrial wastewater pipeline to a natural body of water. This change underlines the success of sustainable environmental projects and their positive impact on local flora and fauna. It impressively demonstrates how previously polluted areas can be revitalized through targeted measures.

Admittedly, the approach to the 150m high heap is very strenuous and involves a few meters of altitude, which I sometimes had to push to complete. But the view makes up for it and on the Halden plateau, which is equipped with a cycle route, there are also beautiful objects to visit with a sundial and horizon observatory, even visible from the A2.

The horizon observatory was set up on the northern summit plateau in 2008. The modern building consists of a circular, flat area with a diameter of 88 m, a forum lowered by 1.50 m with a diameter of 35 m in the middle and two arches with a radius of approx. 45 m, which are like the great circles meridian and celestial equator stretch across the square.

The Emscher has been beautifully renatured. The paths are wide and partly passable. However, there are very few places to rest.
