Just as many of Hitler’s scientists would soon become American scientists, so would many of the Reich’s headquarters and command posts become key facilities used for Operation Paperclip. Castle Kransberg also had a storied past in the history of warfare.

Battles had been waged in this region, on and off, for over two thousand years.
