Spend a night alone at the Energeticon Alsdorf experience museum. Here you can have your own underground experience. If you can make your way through the longwall, you’ll find the climb out to the outdoor area, where you can explore the huge engines, locomotives and train cars in the dark. Then it’s back inside the forge building. There you will discover the most exciting corners of the Energeticon and then snuggle up in your sleeperoo. The silence in the museum will take you to the land of dreams.
