This is originally the oldest church in Vienna, built in the 4th century on the Roman city of Windobona. But the present church, the St. Peter's Basilica, was built between 1701 and 1733. It was inspired by St. Peter's Basilica in Rome and in fact was the first in Vienna to have a dome top.
If the dome’s exterior looks impressive and luxurious, wait until you enter inside. Gilded wood carvings, art objects and murals - all make the wandering in it especially experiential. The round windows under the colorful dome bring in a little light and create a magical atmosphere. The frescoes, originally decorated the walls of the church, were painted by the famous Italian artist Andrea Pauza. However, in 1713 the frescoes were replaced by others.
On the inside of the dome you can see the magnificent work of art - Miriam's coronation scene. Also on the high altar can be seen the Christian saints Saint Peter and Saint John, who are in Jerusalem.
