The Underground Complex
"Der Riese"
"Der Riese", ("The Giant" in English), is located in the
"Gory Sowie" or Owl Mountains of modern-day Poland. It
consisted of seven undergound complexes which concerned
themselves with the mining, refining, research and
development of uranium both for energy producing machines
and weapons of war. The tunnels of the larger complexes are
almost two miles in length. Courtesy of Robert
