Opernpassage

The Opernpassage is an underground passage system beneath Vienna's streets, featuring curved glass windows and checkered floor patterns throughout its corridors. The system connects several locations from the Secession Building to Karlsplatz, providing underground access to the Vienna State Opera and public transportation hubs.

The underground passage opened on November 4, 1955, marking a significant development in Vienna's urban infrastructure alongside the reopening of the Vienna State Opera. The Federal Office for the Protection of Monuments carried out a comprehensive restoration in 2013, preserving original elements such as round columns and shop window designs.

The western section displays a permanent art installation called 'Pi' by Canadian artist Ken Lum, bringing contemporary artistic elements into the space. This work creates a contrast between the classical architecture and modern creation that visitors encounter while walking through.

The passage is easily accessible and offers a protected underground route between various important locations in central Vienna. The best time to visit is during daylight hours when natural light filters through the curved glass windows, making the spaces brighter.

The passage connects the famous Secession building with Karlsplatz, creating a direct route that many visitors never notice even though they walk past it daily. This hidden connection underground has helped keep the streets above less crowded.
