Vienna

Vienna, home to Mozart, Beethoven, Freud, and Klimt, reigns as Europe's music and culture capital, drawing 17 million tourists annually—nearly 4 times #8 Lisbon's 4.5 million. Schönbrunn Palace alone hosts 1.9 million visitors per year, while the Vienna Philharmonic (founded 1842) attracts classical music lovers worldwide. The city's imperial coffeehouses, with 200-year-old traditions, serve more Sachertorte slices per capita than any other European capital. For those who value high art and refined elegance, Vienna's 1.5 million museum visitors per year (Kunsthistorisches Museum) easily outpaces the cultural offerings of #5 Prague.
