Karlskirche is one of Vienna’s most distinctive Baroque churches, rising above the reflecting pool at Karlsplatz. Its grand dome, classical portico and twin columns inspired by Rome’s Trajan’s Column make for an unusually theatrical composition, even by Viennese standards.
Emperor Charles VI commissioned the church after the plague of 1713, dedicating it to Saint Charles Borromeo, a patron associated with plague sufferers. Designed by Johann Bernhard Fischer von Erlach and completed by his son Joseph Emanuel, it was built between 1716 and 1737. Inside, Johann Michael Rottmayr’s vast dome fresco brings the story of the saint’s intercession to life in a swirl of figures and colour.
Visit on a clear morning for reflections in the pool and a quieter look at the interior. Check current opening times, ticket prices and dome access before going, as these can change for services or events. Karlsplatz is an easy stop on the U-Bahn; allow a little time afterward to explore the square and its Otto Wagner pavilions.
