In Salzburg, the present is almost invisible yet always palpable, intertwined with the abysses of its National Socialist past. In a confined space, Hitler's and Himmler's centers of power are linked to the fates of local resistors. Contrasts that this new travel guide makes accessible for the first time. In the shadow of Mozart balls and magnificent mountains, one can find countless dark spots of the past in Salzburg. Hitler's global power center was located on the Obersalzberg. The mass murderer Heinrich Himmler lived in the villa that had been stolen from the Trapp family. To the northwest of Salzburg lies Hitler's birthplace, Braunau. At the Salzburg House of Nature, scientists indulged in racial madness and Tibetan esotericism. On the other side, the courageous Sister Anna Bertha Königsegg fought against euthanasia. It is no surprise that Salzburg leaves no one indifferent.
