Kehlsteinhaus (Eagle's Nest)

The Kehlsteinhaus, also known as "Hitler's Tea House" or the Eagle's Nest, was built as a 50th birthday present for Adolf Hitler from the Nazi Party. The Eagle's Nest was meant to be a retreat for Hitler and a place for him to entertain visiting dignitaries (which he almost never did here). It was commissioned by Martin Bormann, with construction proceeding over a 13-month period prior to its formal presentation to Hitler in 1939. More information and photographs here.
