Hitler's Eagle's Nest (Kehlsteinhaus)
The shot was taken from one of the highest points of Bavarian mountains located at Austrian & German border. It was so high you have walk through passing clouds and chilly wind.
In just another 5 mins entire place was covered with clouds and visibility was zero. On the right hand bottom of the image you can see the clouds just coming in.
This is single RAW file straight from the camera other than slightly tweaking curves in photoshop.
The Kehlsteinhaus (also known as the Eagle's Nest), is a chalet-style building which when built was an extension of the Obersalzberg complex built by the Nazis in the German Alps near Berchtesgaden. The Kehlsteinhaus was an official 50th birthday present for Adolf Hitler. Nicknamed Eagle's Nest by a French diplomat, it was meant to be a retreat for Hitler and a place for him to entertain visiting dignitaries.
