Adlerhorst
Adlerhorst (Eagle's eyrie) was a World War II bunker complex in Germany, located in the rural area of Langenhain-Ziegenberg, Wiesental Wetterau and Kransberg in the Taunus mountains in the state of Hesse.
Designed by Albert Speer as Adolf Hitler's main military command complex, it was reassigned by Hitler in February 1940 to Luftwaffe chief Hermann Göring as his headquarters for the Battle of Britain, serving as Hitler's only during the 1944–5 Ardennes Offensive.
