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.
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.
