It's hard to imagine the peaceful Alpine beauty of Bavaria's mountaintops could ever be the scene for evil to be hatched, but this bright unspoiled wilderness has a sinister past. Turn the clocks back to 1930s Germany, and discover the place where Europe's darkest hour was planned.
Visit the NS-Documentation Center and get a harrowing reminder of the crimes against humanity that were concocted by Hitler and the Nazi party.
It's almost impossible to fathom how Europe's post-war scars can be traced to such a place of tranquil beauty. But this was the place where Hitler and members of the Nazi High Command met in secret to discuss plans for the Third Reich's domination of Europe and the world.
See the famous Eagle's Nest perched precariously on top of Obersalzberg. The remoteness of the location meant it was a safe venue for Hitler's inner circle to meet.
But his fear of heights meant that he actually hated the place - leave it to Hitler to hate anything beautiful. The building is now a restaurant and visitor center.
