Stephen's Cathedral is a landmark building in Vienna. It is one of the three cathedrals in Europe, just like the guardian of Vienna. It was first built in the name of the Roman church. In the 14th century, Rudolph IV ordered a large-scale reconstruction. After being burned by the smoke of World War II, it was rebuilt several times before it formed the present Gothic cathedral. The funerals of Austrian emperors were held here. Since the late 15th century, Stephen's Cathedral has been the Catholic bishop. The church consists of a main building and three towers. The tall conical spires soar into the sky. The colorful roofs with blue and yellow patchwork tiles shine in the sunshine. The armband patterns of tiles and the double-headed Eagles representing the Habsburg Dynasty are spectacular. The interior of the church has undergone several renovations, in which various European architectural arts are compromised and absorbed.
