Architecture in Vienna, Austria
A variety of architectural styles can be found in Vienna, such as the Romanesque Ruprechtskirche and the Baroque Karlskirche. Styles range from classicist buildings to modern architecture. Art Nouveau left many architectural traces in Vienna. The Secession, Karlsplatz Stadtbahn Station, and the Kirche am Steinhof by Otto Wagner rank among the best known examples of Art Nouveau in the world.
The Hundertwasserhaus by Friedensreich Hundertwasser, designed to counter the clinical look of modern architecture, is one of Vienna's most popular tourist attractions. Another example of unique architecture is the Wotrubakirche by sculptor Fritz Wotruba.
In the 1990s, a number of quarters were adapted and extensive building projects were implemented in the areas around Donaustadt (north of the Danube) and Wienerberg (in southern Vienna). The 202 m-high Millennium Tower located at Handelskai is the highest building in Vienna. In recent years, Vienna has seen numerous architecture projects completed which combine modern architectural elements with old buildings, such as the remodelling and revitalisation of the old Gasometer in 2001.
Most buildings in Vienna are relatively low; there are currently (early 2006) around 100 buildings higher than 40 m. The number of high-rise buildings is kept low by building legislation aimed at preserving green areas and districts designated as world cultural heritage. Strong rules apply to the planning, authorisation and construction of high-rise buildings. Consequently, much of the inner city is a high-rise free zone.
