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 psychoanalyst – Sigmund Freud. The city's roots lie in early Celtic and Roman settlements that transformed into a Medieval and Baroque city, and then 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 UN-Habitat classified Vienna as the most prosperous city in the world in 2012/2013. The city was ranked 1st globally for its culture of innovation in 2007 and 2008, and sixth globally (out of 256 cities) in the 2014 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.
Between 2005 and 2010, Vienna was the world's number-one destination for international congresses and conventions. It attracts over 6.8 million tourists a year.
The English name Vienna is borrowed from the homonymous Italian version of the city's name or the French Vienne. The etymology of the city's name is still subject to scholarly dispute. Some claim that the name comes from Vedunia, meaning "forest stream", which subsequently produced the Old High GermanUuenia (Wenia in modern writing), the New High GermanWien and its dialectal variant Wean.
Others believe that the name comes from the Roman settlement name of Celtic extraction Vindobona, probably meaning "fair village, white settlement" from Celtic roots, vindo-, meaning "bright" or "fair" – as in the Irish fionn and the Welsh gwyn –, and -bona "village, settlement". The Celtic word Vindos may reflect a widespread prehistorical cult of Vindos, a Celtic God. A variant of this Celtic name could be preserved in the Czech, Slovak and Polish names of the city (Vídeň, Viedeň and Wiedeń respectively) and in that of the city's district Wieden.
