An interior photograph of the Herzgruft, or Heart-crypt, at the HofburgAugustinerkirche in Vienna. The small crypt contains fifty-four urns, each holding the preserved heart of a member of House Hapsburg. The tradition of interring the heart of deceased Hapsburgs began with King Ferdinand IV on the 10th July 1654 as an act of piety and ended with that of Archduke Franz Karl of Austria on the 8th March 1878. In Urn 42, at the tenth position on the bottom row and mantled with a ribbon of the French Tricolore, is the heart of Prince Napoleon II of France, briefly, and by all intents and purposes in name only, Emperor of the French for fifteen days in 1815, a title only held in pretense after this period.
