Located in the heart of the old town, this Italian-style protagonist church was built in early 774 and has been expanded, refurbished, destroyed and rebuilt over and over again until the Archbishop's Paris Lodron period. The bishop is influenced by the architectural style of the Italian church. Most of the streets here are relatively narrow, but they are very wide near the protagonist church. Although the protagonist church is not as grand as the many churches in Europe, and can not compare the interiors of many Baroque churches, it is the most famous church building in the north, and it also affects Austria. And the architectural style of southern Germany. The walls in the church are dominated by elegant gray and white, and the baroque complex and exaggerated expressions are displayed on the carved beams. Looking up, the dome of the cathedral is very beautiful, like a kaleidoscope, each dome is engraved with different angels and symmetrical patterns, so meticulously detailed. From the stairs outside the church gate to the second floor, from here you can enter the exhibition hall. The Salzburg Cathedral, which was a combination of politics and politics at the time, was not only a symbol of the bishop's rule, but also a luxurious archbishop's residence. Not only did it house a large collection of precious collections, but the bishop's various living quarters were also well preserved.
