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.

The decision was made to use dimension stone for the exterior of the building. Due to the monumental demand for stone, stone from Sóskút, widely used in Budapest, was also used. Three Viennese masonry companies were employed to supply enough masonry labour: Eduard Hauser (still in existence today), Anton Wasserburger and Moritz Pranter. The foundation stone was laid on 20 May 1863.
