Karlskirche - St. Charles' Church in Vienna - St. Charles Borromeo - is considered the most important sacred building north of the Alps. It was built at the behest of Emperor Charles VI in 1716, after the last great plague epidemic, and was completed in 1737.
In 1741, Antonio Vivaldi was buried right next to the Karlskirche. It was the imperial patron church until 1918. Today, you can experience authentic concerts in the Karlskirche with the Orchestra 1756 and its soloists playing baroque instruments.
