Between 2006 and 2008 the caves were converted into a Cave Experience Centre (HöhlenErlebnisZentrum). A clearly visible cubic building was constructed next to the car park and the B 242. This so-called Museum am Berg (museum on the mountain) has a , 17 to 19-degree sloping tunnel (Museum im Berg) linking it to the old Iberg Dripstone Cave. This expansion and conversion has the clear imprint of the district conservationist, Prof. Dr. Reinhard Roseneck, who two years earlier had come up with a new concept for the Cistercian abbey at Walkenried. The cost of the conversion was 3.85 million euros.
