The Giele Botter nature reserve is a former open-cast mining area in southwestern Luxembourg, serving today as an impressive example of nature's reclamation. The name means 'Yellow Butter' in the local dialect, referring to the color of the iron-bearing rock that was mined here for decades. After mining ceased in 1977, the approximately 100-hectare area evolved into a valuable biotope with enormous biodiversity. The terraced landscape still recalls the extraction of minette ores, which laid the foundation for Luxembourg's prosperity. Today, rare orchid species, amphibians in the resulting ponds, and a variety of protected bird species can be found here. A marked educational trail leads visitors through various stages of vegetation succession and features views of the red rock walls characteristic of the Terres Rouges region. Giele Botter has been under nature protection since 1991 and is part of the European Natura 2000 network. It is a place of silence that connects the country's industrial past with a new, wild nature.
