Nürnberger Burg
Since 1594, the Imperial Diet had met only in Regensburg. The Peace of Westphalia of 1648 not only ended the atrocities of the war, but led to the Perpetual Diet of Regensburg which from 1663 to 1806 seated in Regensburg. As a consequence, the Nuremberg Castle lost practically all of its importance and was left undisturbed by outside forces.
