Dokumentationszentrum Obersalzberg, History museum in Berchtesgaden, Germany

The Dokumentationszentrum Obersalzberg is a museum in Berchtesgaden that documents the Nazi regime's presence and operations in this mountain region. The exhibition presents objects, photographs, and documents from that era while explaining how authority was organized and maintained.

The museum opened on 20 October 1999, built on the foundation walls of the Hoher Göll guesthouse, part of the Platterhof hotel complex inside the Führersperrgebiet. Hitler first holidayed at Obersalzberg from 1923 and rented Haus Wachenfeld in October 1928, buying it in summer 1933 and rebuilding it as the Berghof. After the war the area served US forces as a recreation centre from 1953 to 1996; the museum reopened with an extension on 27 September 2023.

The site takes its name from the mountain where Hitler's residence once stood and now serves as a place to understand how power was exercised during the Nazi period. Visitors can see how daily life, decision-making, and ideology were connected in this location.

The museum stands on the slope of the Obersalzberg, not on a summit, and is reached by road from Berchtesgaden; the bus stop for the Kehlsteinhaus is close by. The exhibition runs through two floors of the main building and continues along a tunnel into the bunker, where only part of the shelter network is open.

The museum incorporates original bunkers and underground rooms from the historical site as part of its exhibition. Visitors can descend into these authentic spaces and gain a direct sense of what the location was like.
