[1] Located in the German state of Bavaria, close to the Austrian border, Obersalzberg in the 19th century was one of the earliest tourist destinations in the Berchtesgaden Alps.

That changed, when Hitler purchased the Berghof (Mountain House) residence upon the Nazi seizure of power in 1933 and a large area was cordoned off and evacuated.

[6] After the withdrawal of the US forces in 1996, the Bavarian state government resumed its plans to have a luxury hotel erected, but also the documentation center on the Nazi past in order to prevent the re-opened area becoming a pilgrimage site for Neo-Nazis.

It offers over 950 documents, photographs, audio clips, films and maps as well as a scale model of the Obersalzberg area overlaying current buildings with the position of historical Nazi installations.

The ground floor of the main building and most of the tunnel exhibits cover general topics of Nazi Germany, such as "The Fuehrer", "Actors in the regime", "Machinery of Terror", "Resistance", "Foreign Policy" etc.
