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.
Konzerthaus, Vienna
In 1890, the first ideas for a "Haus für Musikfeste" (House for music festivals) came about. The idea of the new multi-purpose building was to be more interesting to the broader public than the traditional Vienna Musikverein. In addition to the concert hall, the first drawings by Ludwig Baumann for the "Olympion" included an ice-skating area and a bicycle club. In an attached open air area, 40,000 visitors would be able to attend events. The drawings were not accepted. However, today an ice skating area is situated right next to the building.
