The Geleucht (Rheinpreußen Spoil Heap)

"... It is the largest miner's lamp in the world, which thousands of drivers see every day on the Rhine bridge on the A42 from Duisburg - the Internet encyclopedia Wikipedia even describes it as "the largest mining work of art in the world." It rises high above Moers The so-called Geleucht is one of the most impressive and beautiful landmarks in the Ruhr area. It is beautiful to see not only during the day, but also at dusk. It stands on a tailings pile from the Rheinpreußen colliery, which is one of the highest in the area.
Not quite at the highest point, but still on the summit plateau, is the beautiful miner's lamp. A so-called light, of course in a handy design, used to be an indispensable tool in mining, as this aid was usually the only source of light for the miner underground in the pitch-dark tunnel. This example is a special design, the so-called Davy's lamp or Davy's lamp, which, despite the open fire, prevented mine gas from igniting thanks to a special grid construction and was therefore vital. But the lamp was not only a small lifesaver by providing light: the miner's lamps (including the later electric lights) usually marked whether all the miners of a shift had returned safely to daylight. If a lamp was missing, it could be assumed that the owner was still underground and possibly in trouble.
The 30 meter oversized landmark, painted bright red, was designed by Otto Piene (1928-2014), presented at the turn of the millennium and finally built in 2007 with great private commitment and the support of some investors. The inauguration took place on September 17, 2007. You can climb the inside of the Geucht on some dates during the day and use it as an even higher viewing point. ..."

The work created by Otto Piene is reminiscent of a very important utensil in mining: the miner's lamp that gives light in the dark, without which a miner would have been lost. And not just any, but the safest miner's lamp of all: The Davy lamp, created in the 19th century. Due to the lamellar structure of the "light", the illumination seems to have a partly direct but also indirect effect. The place in front of the "Geluchte" is also worth seeing. Deep red settles over the hill. The approximately 8,000 square meter “illuminated area” invites you to linger and relax after the ascent. You can also discover the dump and the "Geluchte" during guided hikes - both during the day and after dark.
