Halde Haniel – a magnificent view of the Ruhr area The Halde Haniel was created from the waste material from the Prosper-Haniel mine. You will find it in the city of Bottrop and have the opportunity to climb up to a height of 185 metres. Since the northern section of the Halde Haniel is still used for the embankment today, you cannot enter this part. In total, however, the freely accessible area of ​​the slag heap extends over 114 hectares - thus the Halde Haniel more space for exploration than most other slag heaps in the Ruhr area. The climb to the summitIf you reach the summit of the Halde Haniel If you want to climb the mountain, you will pass a depiction of the Way of the Cross: The Passion of Christ is depicted in 15 sections by the visual artist Tisa von der Schulenburg. As you walk along the path, you will also have a look at the history of the Halde Haniel: Historical mining tools can be seen along the route. When you reach the top, you will notice the imposing cross by the Oberhausen artist Adolf Radecki, which marks the end of the Way of the Cross. It dates back to the visit of Pope John Paul II, who was in the region in 1987. Culture at lofty heightsThe highlight of the slag heap is the amphitheater on the roof of the slag heap. Various cultural events take place there - almost like the Romans did. The colorful railway sleepers, the "Totems", an installation by the Basque artist Augustín Ibarrola, add colorful accents to the edge of the slag heap. In addition, you have a great view of the surrounding area from up here. In the distance you can see the Bottrop Tetrahedron or the Hoheward slag heap in Herten.
