Linz: The town where Adolf Hitler spent his youth ("Jugendstadt des Führers"), and his planned retirement home after the war. Hitler wanted to turn Linz into a "German Budapest" – a city which, in Hitler's mind, then surpassed German cities of the Danube in beauty. Linz was to be "the new metropolis of the Danube," eclipsing Vienna, a city he hated.[4] Linz was to expand three or four times from its then current size, with Reichswerke Hermann Göring providing jobs for the laborers relocating from Vienna.[5] The bank of the Danube was to be built up with magnificent private homes, and a new "Hitler Centre" (Hitlerzentrum) was to be furbished with new community buildings.[5] Major intended building projects were a Strength through Joy hotel, new municipal buildings designed by Hermann Giesler, a NSDAP party house designed by Roderich Fick, a Wehrmacht Headquarters, an Olympic Stadium, and "as a counter to the pseudo-science of the Catholic Church" an observatory representing "the three great cosmological conceptions of history — those of Ptolemy, of Copernicus and of Hörbiger."[4] A new Gau house for Reichsgau Oberdonau was to feature a hall and a tower, under which Hitler's crypt was to be located.[6] Monuments and buildings to commemorate the Anschluss and Anton Bruckner were also planned.[6] A gigantic suspension bridge was to connect the banks of the Danube, which was to have a decorative frieze depicting the Nibelungen saga with monumental equestrian statues in pairs of Siegfried and Kriemhild and Gunther and Brünhild.[7] The Führermuseum, featuring a 150-metre (490 ft) long colonnade, was to contain the largest and most comprehensive painting collection in Europe,[5] built around the art the Nazis had looted from Western Europe and stolen from rich Jews in Germany.
