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.
Archbasilica of St. John Lateran
The archbasilica is sited in the City of Rome. It is outside Vatican City, which is approximately to its northwest, although the archbasilica and its adjoining edifices have extraterritorial status from Italy as one of the properties of the Holy See, pursuant to the Lateran Treaty of 1929.
