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 International Centre
The VIC, designed by Austrian architect Johann Staber, was built between 1973 and 1979 just north of the river Danube.
The initial idea of setting up an international organization in Vienna came from the Chancellor of Austria Dr. Bruno Kreisky.
