Vienna is the capital of the Republic of Austria and by far its most populous city, with an urban population of 1.7 million and a metropolitan population of 2.4 million. Vienna has a rich history as the capital city of the monarchy and thus abundant historical buildings and museums. The most of these, including Stephansdom (St. Stephen's Cathedral) and the two most well-known museums, Kunsthistorisches Museum (Museum of Fine Arts) and Albertina, are located in the Innere Stadt. The Schloss Schönbrunn palace, a part of the UNESCO World heritage list, is located in the Outer West district. This book offers information on Vienna and its most notable places.
