Description & Facts: To the traveler, the city has a very convenient layout: The 'old town', or city center, is the first district, with the Stephansdom and Stephansplatz at the centre of a bullseye. It is encircled by the Ringstrasse (Ring Road), a grand boulevard constructed along the old city walls, which were torn down at the end of the 19th century. Along the Ringstrasse are many famous and grand buildings, including the Rathaus [City Hall], the Austrian Parliament, the Hofburg Palace, the Natural History Museum, the Museum of Art History (Kunsthistorisches Museum), and the State Opera House. Districts 2-9 are mostly gathered within the G?¦rtel ('belt') Road, which runs parallel to and encircles the Ringstrasse like an outer belt. In these districts you can find the Prater (amusement) park and the other, hip quarters of the Second District (close to Schwedenplatz) as well as the Jewish quarter, S?¦dbahnhof (southern Rail Station) and Westbahnhof (Western Railstation) - a major national and international railway terminus, currently undergoing massive renovation (see travel) - from which the major shopping street Mariahilfer Strasse leads eastwards toward the inner city, the Hundertwasserhaus and Hundertwasser Kunsthaus in the 3rd, and the Belvedere Palace. Outside the "belt" road, among other sites are the Danube Tower (Donauturm) and notably Sch??nbrunn Palace, which is one of the most visited tourist attractions and deservedly so. It was placed on the UNESCO World Cultural Heritage List in 1996. The Vienna Tourist Board operates information and booking booths at the airport Arrival Hall, 7AM-11PM and in town at Vienna 1, Albertinaplatz/Maysedergasse.
