For decades the Rhein-Ruhr area (Ruhrgebiet) in Northrhine-Westfalia (NRW) was marked by intensive steel industry and coal mines. Due to globalization partially pared with cutthroat competition, this industry went into a deep structural crisis. A lot of companies had to close business in the early eighties. Subsequently countless heaps, previously used by the coal mines as slag heaps, were re-natured in the nineties. On some of these heaps artwork was constructed, landmarks, which can be seen from far in the Ruhrgebiet. Some of them are even illuminated at night. These heaps are center of attraction for photographers and people looking for recreation.

Halde Brockenscheidt

The slag heap Brockenscheidt is located next to the former coal mine Zeche Waltrop, which was closed 1979. The slag heap is only 15m high and one of the smallest heaps in the area. In 2000 a artist constructed the Spurwerkturm, a sculpture of 20m height, which on purpose is "unfinished", as one can see at the top of the pyramid. Visitors can climb the stairs to a visitor platform at 12m height.

Halde Schwerin

The slag heap "Schwerin" is located close to Castrop-Rauxel. The name is derived from the former coal mine "Graf Schwerin", which closed business in 1967. The artist Jan Bormann constructed a sun dial on top of the heap at 150m height. The clock consists of 24 metallic pillars and a clock hand which points to the mid of the construction. The sculpture is 10 meters high and indicates the middle-European winter time. The sundial is not normalized to Castrop-Rauxel, but to the 15th degree of latitude, which determines the middle-European time. This is why the sundial is 30 minutes fast, as desired by the artist.

Halde Rheinelbe

The slag heap "Rheinelbe" is located next to Gelsenkirchen-Ückendorf. The coal mine of the same name closed business already in 1928. The slag heap was used by other coal mines in the surroundings until 1974. End of the seventies the municipality started to revegetate the heap. But the former slag heap is burning in its inside. Remains of coal in the heap self-inflamed due to undesired access of oxygen. Authorities did not succeed to extinct the smoldering of the heap until today.  The spiral hill (Spiralberg) is located on top of the heap at 100m height. On top of this hill artist Herman Priegann constructed a sculpture out of debris of the former coal mine. Stairs made out of concrete lead to this landmark. The artwork is called Sky Stairs (Himmelstreppe).

Halde Großes Holz

The slag heap Großes Holz is located in Bergkamen, Germany. Blue light houses and blue blooming flowers are composed in a way that it reminds of a blue ribbon across the hill, a symbol of Bergkamen. The height Adener Höhe reaches high above the ground and allows a fantastic panoramic view over the region. A 30m high sculpture is constructed on top of the heap, which is illuminated at night.

Schurenbachhalde

With 100m length and 50m width, "Schurenbachhalde" is one of the bigger slag heaps in the Ruhrgebiet. The name is inherited from a small river on which the heap was built. On top of the heap there is a artwork "Bramme for the Ruhrgebiet", a rectangular piece of steel with a height of 15 meters, a width of 4 meters. The steel is approximately 10cm thick. The landmark was constructed in 1998 by the American artist Richard Serra. Irony is that the steel had to be produced in France, because there was no steel mill existing anymore in Germany, that had the capabilities to produce steel of this size.
