The Gästehaus Hoher Göll was originally a guesthouse associated with Mauritia Mayer’s Pension Moritz. Along with the Platterhof, the guesthouse was enlarged and renovated. It was intended to be an intimate guesthouse for visiting dignitaries, and some did stay there, but it was mainly used as administrative offices for Reichsleiter Martin Bormann’s staff, and for special guests of Bormann.
The Gästehaus was not materially damaged in the 1945 bombing, but it fell prey to plunderers and was allowed to fall into disrepair. For many years it was one of the few Nazi ruins on the Obersalzberg that were substantially intact. After return of the area in 1995, the Bavarian government decided to open a Documentation Center on the Third Reich. The ruins of the Hoher Göll were almost entirely torn down — saving only the lower front façade and parts of the basement — and the building was rebuilt. Today it hosts the Obersalzberg documentation center. Part of the bunker complex can be visited from the basement of the Documentation Center.
