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.
Cardinal Vicar
In 1929, with the establishment of Vatican City, Pope Pius XII removed Vatican City State from the authority of the Cardinal Vicar. Pope John XXIII established that the offices of the vicarate would be located at the Lateran Palace. Pope John Paul II reorganized the vicarate with the Apostolic constitution "Ecclesia in Urbe", to bring the structure of the vicarate more in line with the 1983 Code of Canon Law.
