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.
Rome
Rome has been a major Christian pilgrimage site since the Middle Ages. People from all over the Christian world visit Vatican City, within the city of Rome, the seat of the papacy. The Pope was the most influential figure during the Middle Ages. The city became a major pilgrimage site during the Middle Ages and the focus of struggles between the Papacy and the Holy Roman Empire starting with Charlemagne, who was crowned its first emperor in Rome in 800 by Pope Leo III. Apart from brief periods as an independent city during the Middle Ages, Rome kept its status as Papal capital and "holy city" for centuries, even when the Papacy briefly relocated to Avignon (1309–1377). Catholics believe that the Vatican is the last resting place of St. Peter.
