The Kehlsteinhaus or "Eagle's Nest". This building is also often called "Hitler's Tea House," but that is a misnomer. Although Reichsleiter Martin Bormann was inspired to build the Kehlsteinhaus by Hitler's obvious fancy for the Teehaus on the Mooslahnerkopf, Hitler did not use the Kehlsteinhaus as an afternoon tea house, nor did he visit it regularly. Hitler used the Kehlsteinhaus only to show off to visiting dignitaries, and he probably did not visit it himself more than twenty times (at the most), as he did not like the height and the resulting changes in air pressure, and the perceived dangers of lightning and the elevator. Bormann himself and Eva Braun did far more entertaining in the Kehlsteinhaus than did Hitler. The Kehlsteinhaus was the pinnacle of Bormann's building mania on the Obersalzberg, literally and figuratively. It was an engineering marvel of its day -- the house was built on a rocky spur of the Hoher Göll mountain, some 2700 feet above the Obersalzberg (6017 feet above sea level). To reach this spur, a mountain road of some four miles was blasted into the mountainside, using only one hairpin curve (switchback), and five tunnels. The house itself is reached by a tunnel driven 407 feet into the mountain, at the end of which is a large brass elevator that rises 407 feet to the building. This was actually a two-story elevator: an upper car which stopped on the main level, and a lower car that stopped in the basement for resupply of the kitchens. The road and house were built in only 13 months, to be presented to Hitler on his 50th birthday in 1939.
