Obersalzberg

The lovely town of Berchtesgaden is in the Bavarian Alps, much visited for its wildly decorative Baroque architecture. High above perches Obersalzberg, an enclave that is world-known as the location of the country retreats of Nazi party leaders Adolf Hitler, Martin Bormann and Hermann Göring. On the site of the former Nazi stronghold is the Dokumentation Obersalzberg, a peace center-cum-museum designed to deal with the horrors of National Socialism and examine the history of World War II; it also incorporates sections of a Nazi underground bunker system. 
From Obersalzberg transport runs up to Hitler’s infamous guesthouse, the Kehlsteinhaus (Eagle’s Nest), which sits even higher at 6,600 feet (2,011 m) above the spectacular Berchtesgaden valley; it has been open since 1952 as a restaurant with views across to the peak of Untersberg. 

Practical Info

Eagle’s Nest is only open during summer and is accessible via a complicated combination of tunnel and elevator up the steep rocky sides of Kehlstein or by a switchback road carved out of the hillside. Berchtesgaden is over the Austrian border in Germany but passports are not needed as both countries are members of the EU.
