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.
Demographics of Italy
The Italian Catholic Church is part of the global Roman Catholic Church, under the leadership of the Pope, curia in Rome, and the Conference of Italian Bishops. In addition to Italy, two other sovereign nations are included in Italian-based dioceses, San Marino and Vatican City. There are 225 dioceses in the Italian Catholic Church, see further in this article and in the article List of the Roman Catholic dioceses in Italy. Even though by law Vatican City is not part of Italy, it is in Rome, and along with Latin, Italian is the most spoken and second language of the Roman Curia.
