Tourism in Vatican City
The Vatican was built during the year 326 A.D. As the population and housing grew, the first palace was built during the 5th century under the reign of Pope Symmachus (498–514). Under the Holy Roman Empire, the Papal States grew to include a large portion of central Italy. But since the unification of Italy in the mid-19th century, Vatican City is the only papal state that has survived. As of 1929, because of the Lateran Treaty, the Vatican is recognized as its own independent state, the smallest in the world in population and land size, with a population of just over 800 people in July 2011. The Pope is not only the head of the Catholic religion but also head of state for Vatican City. Since the Vatican is located in Italy, the main language of the Vatican state (or Vatican City) is Italian.
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.
