Kehlsteinhaus
The Kehlsteinhaus (known as the Eagle's Nest in English-speaking countries) is a Third Reich-era edifice erected atop the summit of the Kehlstein, a rocky outcrop that rises above the Obersalzberg near the town of Berchtesgaden. It was presented to Adolf Hitler on his 50th birthday as a retreat and place to entertain friends and visiting dignitaries. Today it is open seasonally as a restaurant, beer garden, and tourist site.
