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
Concurrent to the Art Nouveau movement was the Wiener Moderne, during which some architects shunned the use of extraneous adornment. A key architect of this period was Adolf Loos, whose works include the Looshaus (1909), the Kärntner Bar or American Bar (1908) and the Steiner House (1910).
