Some more from the WP:
The Kehlsteinhaus (in English-speaking countries also known as the Eagle's Nest) is a chalet-style structure erected on a subpeak of the Hoher Göll known as the Kehlstein.
It was built as an extension of the Obersalzberg complex erected by the Nazis in the mountains above Berchtesgaden.
The Kehlsteinhaus was intended as a 50th birthday present for Adolf Hitler to serve as a retreat for Hitler and place for him to entertain visiting dignitaries.
