Vatican City
Vatican City has a reasonably well-developed transport network considering its size (consisting mostly of a piazza and walkways). A state that is long and wide, it has a small transportation system with no airports or highways. The only aviation facility in Vatican City is the Vatican City Heliport. Vatican City is one of the few independent countries without an airport, and is served by the airports that serve the city of Rome, Leonardo da Vinci-Fiumicino Airport, and to a lesser extent Ciampino Airport.
Vienna
Vienna is the seat of the Metropolitan Roman Catholic Archdiocese of Vienna, in which is also vested the exempt Ordinariate for Byzantine-rite Catholics in Austria; its current Archbishop is Cardinal Christoph Schönborn. Many Roman Catholic churches in central Vienna feature performances of religious or other music, including masses sung to classical music and organ. Some of Vienna's most significant historical buildings are Roman Catholic churches, including the St. Stephen's Cathedral ("Stephansdom"), Karlskirche, Peterskirche and the Votivkirche. On the banks of the Danube, there is a Buddhist Peace Pagoda, built in 1983 by the monks and nuns of Nipponzan Myohoji.
