Karlskirche (St. Charles' Church), Vienna

The Saint Charles Church (Karlskirche), located on the southern side of the eponymous Charles or Karl Square (Karlsplatz) in Vienna, is recognized as the city's most exceptional baroque temple. This architectural marvel was commissioned by Charles VI, Holy Roman Emperor, in 1713 as a vow for divine relief from the plague, which was fulfilled. The church honors Saint Charles Borromeo, a key figure in the 16th-century Counter-Reformation known for his dedication to plague victims.

Completed in 1737, the church incorporates a blend of architectural styles. Its elongated dome and Greek temple-like façade are complemented by columns inspired by those dedicated to Emperor Trajan in Rome, reflecting Roman baroque influences from artists like Bernini and Borromini. These columns symbolize the vast power of the Habsburgs, likened to the mythological Pillars of Hercules.

The church has historical connections extending beyond its architecture. It is located near the burial site of composer Antonio Vivaldi, who died in 1741, and still hosts Vivaldi concerts, honoring his legacy. On May 28, 1878, Johann Strauss married his second wife at Saint Charles's. Unfortunately, the young lady wasn't keen on Strauss's music, so the marriage ended in divorce four years later. The church is also where actress Hedy Lamarr was married in 1933.

The church's interior is rich in symbolic artistry, intertwining the legacy of Saint Charles Borromeo with imperial themes. This is vividly expressed in the dome fresco, depicting an intercession scene. The church's use of marble and gold enhances the light within the space, emphasizing its majestic ambiance. The pulpit, crafted with detailed walnut carvings, also highlights the church’s historical significance, restored in 2006-2007 to its original splendor.

Tip:
You have to pay to get in (students get a discount), but it's well worth it, if only for the lovely interior alone.
A lift inside can take you close to the murals on the dome ceiling. From up there, you can also enjoy a spectacular view of the city from the dome window.
