Karlskirche
A plague vow turned into Vienna's most architecturally confused church — and it works.

Charles VI swore to build this in 1713, one year after Vienna's last major plague epidemic. Fischer von Erlach answered with a deliberate collision of styles: a Greek temple portico at centre, Roman Baroque tower pavilions on each side, and two columns modeled on Trajan's Column with bas-reliefs. His son shortened the dome after his death. Antonio Vivaldi was buried in the adjacent cemetery in 1741 — his grave is lost, but the church runs regular concerts in his honour.
What to look for
- The two flanking columns crafted by Lorenzo Mattielli — their bas-reliefs are inspired by Trajan's Column in Rome
- The Greek temple portico at the centre of the facade, jarring deliberately against the Baroque towers on either side
- The dome above its high drum — note it was shortened from Fischer von Erlach the elder's original plan by his son
Check the Karlskirche concert schedule before visiting — Vivaldi performances are held regularly inside the church.
