Vienna's inner city comprises the old town, hemmed in by the Ringstrasse. There are over 60 museums here, including the Kunsthistorisches and the Albertina. Almost all sightseeing highlights are located here: the Hofburg as the imposing residence of the Habsburgs, the Vienna City Hall or St. Stephen's Cathedral, the Gothic landmark of Vienna. If you love classical music, visit the world-famous Vienna State Opera, where Mozart's Don Giovanni premiered. At Kohlmarkt, you can store in designer stores by Chanel and reside in hotels that elegantly blend into the cultural ambience.
