The magnificent Opernhaus am Ring, famous first and foremost for its annual high society ball, hosts productions of the very highest quality by the likes of the Vienna Philharmonic Orchestra, the State Ballet Company and a host of world famous opera singers and directors. However, the opera house started its days on a less auspicious note, with architect Eduard van der Nüll committing suicide in 1868 because of intense public criticism of his design. The Opera House opened with Mozart's Don Giovanni in 1869, and has been going strong ever since.
