This small forest Fatima prayer site was built after the Second World War by the Pétange Scouts to thank Mary. The surviving scouts came back from the war or concentration camps in Germany and had decided to build a small chapel to thank the Holy Mother Mary. Every year, on the anniversary of St. Francis of Assisi, the Pétange Scouts celebrate a forest mass at this chapel in October in honor of their deceased members. At the same time, they also built the new scout chalet, which is now located in the nature reserve, with their own hands. By the way, the Pétange Guiden a Scouten (boy scouts) are celebrating their 100th anniversary this year in 2025 Group Saint Francois d'Assisi

Giele Botter, located near Pétange in southwestern Luxembourg, is a nature reserve transformed from a former open-pit iron ore mining site. The name "Giele Botter," meaning "Yellow Butter" in Luxembourgish, reflects the area's distinctive yellowish soil, a remnant of its mining past. Since the cessation of mining activities, the site has undergone significant ecological restoration, now featuring dense forests, shrubs, dry grasslands, and ponds.
