Dokumentationszentrum Obersalzberg

Dokumentation Obersalzberg is a museum in the Obersalzberg resort near Berchtesgaden, providing historical information on the use of the mountainside retreat by Nazi leaders, especially Hitler who regularly vacationed in this area beginning in 1928. The museum was opened in 1999, and by 2007 had been visited by more than one million people.
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 residence upon the Nazi seizure of power in 1933 and a large area was cordoned off and evacuated. After World War II, the premises were handed over to the State of Bavaria, however, they remained occupied by a United States Armed Forces recreation center and the General Walker Hotel for US troops, which had been the original Platterhof luxury hotel that had been used by the Nazis. The hotel was demolished in 2001.
