Introduction to the Augustine Church: The Augustine Church (Augustinerkirche) has been the palace church of the royal family since the 18th century. Royal weddings and funerals were held here. Among them, the most eye-catching wedding was that Napoleon was busy with the war and did not even have time. To attend his wedding to Maria Louise, he had to let someone else perform the wedding on his behalf; the wedding of Franz Joseph and Princess Sissi was also held here.
In addition, the crypt in the Augustinian church contains fifty-four small jars containing the hearts of Habsburg royal relatives. Habsburg funerals were very strange. A body was buried in three places. The heart was placed in the Augustinian church, the other internal organs were placed in the Stephen church, and the bones were placed in the royal crypt. Among the members of the Habsburg dynasty, Napoleon's son died of tuberculosis at the age of 21. His bones were returned to France before World War II, but his heart remained in the Augustinian church forever.
