One of the other most famous landmarks in Vienna this 13th c basilica was built on the site of a 12th C Romanesque sanctuary. It has been badly damaged by both the Ottoman Turks in 1683 and Russian bombs in 1945. It was fully restored in 1948 and reopened with a new roof. The design pattern is typical of a church dedicated to St Stephen, typically seen on churches in Hungary. The steeple rises to an almighty 450 feet while the catacombs offer a macabre display of urns containing the internal organs of the Hapsburg family. Probably started with the collection of Augustinian friars hearts they also have stored down there along with the skeletons of thousands of plague victims.
