Berchtesgaden the Obersalzberg. In order to serve as an outpost of the German "Reichskanzlei" (Imperial Chancellery), Berchtesgaden and its environs ("Stanggass") saw substantial expansion of offices, security, and support services, mainly on the Obersalzberg. Included in the town were a new railway station, with a reception area for Hitler and his guests, and an adjacent post office. The Berchtesgadener Hof Hotel, where famous visitors such as Neville Chamberlain and David Lloyd George stayed, was substantially upgraded. The "Kehlsteinhaus" (known as the "Eagle's Nest" among the Allies) atop the Kehlstein subpeak of the Hoher Goll was built as a present for Hitler's
Berchtesgaden by the Nazis. In 1972, local government reform united the then independent municipalities of Salzberg, Maria Gern and Au (consisting of Oberau and Unterau) under the administration of the town of Berchtesgaden. Another suggested reform uniting all remaining five municipalities in the Berchtesgaden valley (Bischofswiesen, Ramsau, Marktschellenberg and Schönau) failed to gain enough popular support; it passed in Berchtesgaden but failed everywhere else. The Berchtesgaden National Park was established in 1978 and has gradually become one of Berchtesgaden's largest draws. Mass tourism is confined to a few popular spots, leaving the rest to nature-seekers. Other tourist draws are the Königssee,
