Vienna is the capital of the Republic of Austria and by far the largest city in Austria with its population of more than 1.7 million. As you'd expect it's Austria's cultural, economic, and political centre. As the former home of the Habsburg court and its various empires, the city still has the trappings of the imperial capital it once was, and the historic city centre is inscribed on the UNESCO World Heritage List.
Apart from being regarded as the City of Music because of its musical legacy, Vienna is also said to be "The City of Dreams" because it was home to the world's first psycho-analyst - Sigmund Freud. The city's roots lie in early Celtic and Roman settlements that transformed into a Medieval and Baroque city, the capital of the Austro-Hungarian Empire.
It is well known for having played an essential role as a leading European music centre, from the great age of Viennese Classicism through the early part of the 20th century. The historic centre of Vienna is rich in architectural ensembles, including Baroque castles and gardens, and the late-19th-century Ringstrasse lined with grand buildings, monuments and parks.
The city was ranked 1st globally for its culture of innovation in 2007 and 2008, and fifth globally (out of 256 cities) in the 2011 Innovation Cities Index, which analyzed 162 indicators in covering three areas: culture, infrastructure and markets. Vienna regularly hosts urban planning conferences and is often used as a case study by urban planners.
Art and culture had a long tradition in Vienna, including theatre, opera, classical music and fine arts. The Burgtheater is considered one of the best theatres in the German-speaking world alongside its branch, the Akademietheater. The Volkstheater Wien and the Theater in der Josefstadt also enjoy good reputations. There is also a multitude of smaller theatres, in many cases devoted to less mainstream forms of the performing arts, such as modern, experimental plays or cabaret.
Music is one of Vienna's legacies. Musical prodigies including Wolfgang Amadeus Mozart, Joseph Haydn, Ludwig van Beethoven, Franz Schubert, Johannes Brahms, Gustav Mahler and Arnold Schoenberg have worked there.
