Because of Vienna’s historic and cultural prominence (political and economic centre of the Danube Monarchy) and due to its wealth of landmarks, Vienna’s tourism is particularly important. Already in 1883, 200,000 visitors were counted. After the Second World War, Vienna expanded into the centre of Austria’s tourism with its unique cultural features. In 1995, 6064 businesses were active in the catering industry. In 1995, 340 accommodation establishments (thereof 13 5-star-hotels) provided 20,796 rooms with 41,144 guest beds. The number of foreigners staying overnight amounted to 6,111,568 and of natives 938,142 in 1995. With the fall of the Iron Curtain, there was a sudden rise in tourism from the eastern neighbouring states. The number of these primarily day trippers is not reflected in the figures of overnight stays. Typical for city tourism is the short average duration of stay of 2.5 days; in the summer season the bed capacity is working to 52.2%.
Major tourist attractions include the imperial palaces of the Hofburg and Schönbrunn (also home to the world's oldest zoo, Tiergarten Schönbrunn) and the Riesenrad in the Prater. Cultural highlights include the Burgtheater, the Wiener Staatsoper, the Lipizzaner horses at the spanische Hofreitschule and the Vienna Boys' Choir, as well as excursions to Vienna's Heuriger districts.
There are also more than 100 art museums, which together attract over eight million visitors per year. The most popular ones are Albertina, Belvedere, Leopold Museum in the Museumsquartier, KunstHausWien, BA-CA Kunstforum, the twin Kunsthistorisches Museum and Naturhistorisches Museum, and the Technisches Museum Wien, each of which receives over a quarter of a million visitors per year.
There are many popular sites associated with composers who lived in Vienna including Beethoven's various residences and grave at Zentralfriedhof (Central Cemetery) which is the largest cemetery in Vienna and the burial site of many famous people. Mozart has a memorial grave at the Hapsburg gardens and at St. Marx cemetery (where his grave was lost). Vienna's many churches also draw large crowds, the most famous of which are St. Stephen's Cathedral, the Deutschordenskirche, the Jesuitenkirche, the Karlskirche, the Peterskirche, Maria am Gestade, the Minoritenkirche, the Ruprechtskirche, the Schottenkirche and the Votivkirche.
