Emperor Charles VI commissioned the church in the 1710s, fulfilling a vow made during a plague outbreak, and dedicated it to St. Charles Borromeo, a patron saint invoked against the plague. The result, designed by Johann Bernhard Fischer von Erlach, mixes classical, baroque and even vaguely Ottoman-influenced elements into one of Vienna's most original buildings.
The dome lift
What sets Karlskirche apart from the city's other churches is a panorama lift installed inside, originally built for restoration work and now open to visitors. It carries you up close to the vast ceiling fresco by Johann Michael Rottmayr, close enough to make out brushwork invisible from the floor, before a short staircase continues out onto a platform with views over the surrounding rooftops.
Why it's worth the detour
Karlskirche sees a fraction of the crowds that Stephansdom does, which makes it a genuinely peaceful place to sit for a while, and the dome lift is a novelty you won't find at any of Vienna's other major churches. It also sits right on Karlsplatz, next to the Wien Museum and a short walk from the Naschmarkt and the Secession building.
Local tip
Check the opening hours before you go — like most working churches in Vienna, Karlskirche closes to visitors during services.
