Notable items.
There is a large statue of St. Michael on top of the front door of the church. Inside the church, the altarpiece has a large sculpture by Lorenzo Mattielli (1688 – 1748). The sculpture shows Saint Michael sending the bad angels out of Heaven. Below the sculpture, there are statues of two angels holding a picture of the Virgin Mary. 
This church is very near to the Hofburg Palace, the palace of the Holy Roman Emperors. St. Michael's was the parish church of the Emperors and their families. Many famous people are buried in the church. One of them is the Italian poet, Pietro Metastasio. The church has a very large pipe organ. Parts of the organ are covered with gilt (thin sheets of gold). The famous composer, Joseph Haydn, played this organ when he was a very young man. In 1791, parts of Mozart's "Requiem" (music set to the words of the Requiem Mass) were performed for the very first time in St. Michael's Church. They were performed in memory of Mozart by the singers and musicians who worked with him in Vienna.
