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.
Opernpassage
Designed by architect Adolf Hoch it has been a symbol of a modern spirit in architecture and urban planning. After more than 50 years the City of Vienna undertook a complete restoration of the structure, advised by the Federal Office for the Protection of Monuments in Austria. The passage was reopened on 17 September 2013. It shows the original design of the round columns, the curved glass of the shop windows, and the chequerboard pattern of the floor.
