Salzburg can be divided into Salz and Burg, the former meaning German "salt" and the latter meaning "highland". Named for the nearby salt mines and castles, across the grain street, there is an open space called the Bishop's Palace Square. There is a big ball on the square. There are several magnificent Baroque-style buildings in the square. The cathedral is one of them. It was founded by Virgie in 774 and has been built several times. It is said to be the first Baroque-style Church North of the Alps. There is a huge one in the middle of the square. Salzburg is the largest Baroque fountain in Central Europe. More than 1,000 years ago, Salzburg was an independent Church state, and the symbol of the supreme religious power. Therefore, there are many classical buildings left over from its construction. Salzburg Cathedral is one of the most important buildings in the city. The church has gone through eight centuries, storms and storms, from the destruction and reconstruction of the fire, witnessed the historical traces of Salzburg. As a soul Church in Salzburg, it was once a baptismal sanctuary of Mozart, where he served as an organist for many years in his short life, and still displays the organ Mozart played at that time. And the funeral of the famous conductor Karajan was also held in this cathedral. The interior walls of the church are mainly gray and white, and the complex sculptures of Baroque are vividly displayed on the beams and paintings. Inside the main wall of the Cathedral are four giant statues - "St. Peter and Paul with keys and swords, and the state patron saints Rupert and Virgil with salt bottles and church models. The two emblazoned shields represent the two main builders of the cathedral, Marcus Sitikus and Paris Rodrn. The ceiling paintings depict the life and suffering of Jesus. Entering Salzburg Cathedral is attracted by the exquisite sculptures. The most striking one is the organ of the cathedral, which is said to be the first in Europe, with a total of 6,000 organs. A group of pipe organs on the side of the wall is particularly eye-catching, which Mozart used. In the corner of the church, we need a precious cultural relic, the baptismal basin, in which young Mozart was baptized. The Museum of the church is also worth seeing. It contains medieval sculptures of the church and Baroque paintings. To the west of the Bishop's Square, this is the palace of the archbishops who ruled Salzburg for more than a thousand years. The sky is late and they are only in a hurry outside. I took a photo in a hurry, as if I was doing a modern exhibition. It's a pity. Walking out of the church and down the alley beside the square is the fortress of the castle.
