Vienna State Opera
The opera house was the first major building on the Vienna Ringstrasse commissioned by the Viennese "city expansion fund". Work commenced on the house in 1861 and was completed in 1869, following plans drawn up by architects August Sicard von Sicardsburg and Eduard van der Nüll. It was built in the Neo-Renaissance style by the renowned Czech architect and contractor Josef Hlávka.
Vienna State Opera
Lengthy discussion took place about whether the opera house should be restored to its original state on its original site, or whether it should be completely demolished and rebuilt, either on the same location or on a different site. Eventually the decision was made to rebuild the opera house as it had been, and the main restoration experts involved were Ernst Kolb (1948–1952) and Udo Illig (1953–1956).
