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.
Graz Opera
Designed by Ferdinand Fellner and Herman Helmer in the neo-baroque style, the Graz Opera was inaugurated in 1899 with a performance of Schiller's play "William Tell", followed a few days later by Wagner's opera "Lohengrin". The building suffered damage during World War II bombings but was repaired and re-opened after the war. Between 1983 and 1985, it underwent a $15 million renovation which saw the installation of modern equipment and facilities without significantly changing the original exterior and interior of the building.
