About
As of today, seven systems of shelters and tunnels belonging to the “Komplex Riese” are known to exist in the Owl Mountains. The exact purpose of these facilities remains unclear even today. They are all of a similar design, corresponding to the layout of other of Adolf Hitler's subterranean headquarters.
