The so-called Eagle's Nest (Kehlsteinhaus) was built as a teahouse for Adolf Hitler on Kehlstein Moutain at an elevation of 6,017 ft / 1,834 m. Its unusual position made it a unique engineering feat.
The building itself was a project of Martin Bormann's and given to Adolf Hitler for his 50th birthday.
The Eagle's Nest remained unscathed from the bombing of the Allied Forces during WWII.
Since 1952 it has been open to the public as a mountain top restaurant with a spectacular view - which I unfortunately missed due a torrential rain!
