Nuremberg Castle
In "Mein Kampf", Hitler wrote that the Imperial Insignia "were still preserved in Vienna and appeared to act as magical relics rather than as the visible guarantee of an everlasting bond of union. When the Habsburg State crumbled to pieces in 1918, the Austrian Germans instinctively raised an outcry for union with their German fatherland." During the Anschluss, when Austria was annexed to Germany, the Nazis brought the "Reichskleinodien" to Nuremberg, where they displayed them during the September 1938 Party Congress. They then transferred them to the Historischer Kunstbunker, a bunker that had been built into some of the medieval cellars of old houses underneath Nuremberg Castle to protect historic art from air raids.
