Karlskirche
A magnificent religious building with a large cupola: St. Charles' Church, the last work of the eminent baroque architect Johann Bernhard Fischer von Erlach.
The church, finished in 1739 by his son Joseph Emanuel Fischer von Erlach, was built as the result of a vow taken by Emperor Charles VI during a plague epidemic. The church is consecrated to the patron saint of the Habsburg emperor, Saint Charles Borromeo: The exhibits in the small Museo Borromeo include the traveling clothes of the Bishop of Milan.
