Haas-Haus

Modern Haas House was one of the most disputed building projects of the late 20th century in Vienna. Viennese architect Hans Hollein set about to introduce a concrete and glass structure opposite St. Stephen's cathedral, a plan that did not go well with the Viennese population.
The round curve of its facade quotes the ancient Roman citadell Vindobona, whose former layout is traceable throughout Vienna's first district. Medieval houses were built on top of Roman ruins, modern houses were built on top of medieval ruins... Haas House uses this principle to blend into its surrounding despite its contrasting architectural style.
Today, Haas House is one of the most exciting buildings in Vienna and the city's pride. The square of St. Stephen's cathedral is opened up by the glass facade. Images of St. Stephen's Cathedral reflected by the straight glass facade of Haas House are a popular motif.
The interior was designed with attention to detail. At the top you can enjoy a spectacular view of St. Stephen's Cathedral at a beautiful coffee shop and restaurant.
