Phantastenmuseum

Yet another example of the gruesome divide-and-conquer burial strategy of the Habsburg dynasty. It is said that other dynasties waged countless wars to acquire new lands, but "you, happy Austria, marry". Even in death, the Habsburgs placated three different churches with the honor of caring for their remains. The best known, the Kapuzinergruft, contains their actual bodies. St Stephens holds their innards (intestines and other parts taken out during the preservation process). But the Augustinerkirche holds, in the Herzgruft (Heart Crypt), all the Habsburgs' hearts. The tradition began in 1627 with Emperor Ferdinand IV, who wanted to "lay his heart at the feet of the Mother of God", literally. His heart, and those of his descendants, are preserved in silver jars which are carefully cared for by the Augustinian friars who run the church. When the renovation was underway it was found that the preservative in some of the caskets had evaporated over the years, leaving nothing but a dried-out, mummified heart.

This magnificent historic library was designed by Johann Bernhard Fischer von Erlach and built in 1726. As well as the spectacular room itself, you can see temporary exhibitions on various historical subjects.
