Two floor levels of that huge Nazi complex were almost finished when WWII has started.
All buildings got destroyed and the remains after war end were covered with countless tons of Berlin city war (bombs) rubble and sand. All the stuff from downtown was transported by thousands of trucks and by this way the hill was growing yard by yard to its current size. More than 200.000 trees were planted by volunteers. The T-berg complex, about 117 yards above sea level, was located in the British sector of West Berlin.
In 1961, the U.S. National Security Agency (NSA) took over that location for own military purposes. There was no other place which was better located to the Red Army country. There were several constructions and changes in all the years. In that Grunewald area are 2 hills, like twins, side by side, one as public recreation area only, the other one occupied by the U.S. & Brit. Army. The Berliners also used their part of it in the Winter time. It still had some nice toboggan and ski runs downhill.
