Hey I actually live just about 15 miles from this building. I was always fascinated by the old mines of Limburg. By the way the hills aren't natural: they are heaps of garbage that came out of the mine until they were closed (Zolder was the last in 1992). Nowadays they are al green and popular for a nice one hour climb for a terrific view of the surrounding towns.
