Some facts and figures:
Vatican City is unique in the world. It is at the same time the headquarters of the Roman Catholic Church, and actually an independent country. The pope is the only completely sovereign man on earth - he is an absolute ruler who is subject to no other human being's authority, religious or political.
In accordance with the Lateran Treaty which was signed in 1929 between Cardinal Gasparri and Italian dictator Benito Mussolini, Vatican territory consists of slightly more than 108 acres (44 hectares), which are completely enclosed by the city of Rome, Italy.
Vatican City includes St. Peter's Church, the Papal Palace, the Vatican Museums, the Vatican Gardens, the Vatican Library, Belvedere Park, and other buildings between Viale Vaticano and the Church. A few other buildings in Rome outside of Vatican City boundaries have extraterritorial rights.
It has a population of less than 1,000.
The Swiss Guards are responsible for the pope's personal security.
Vatican City issues its own currency and postage stamps, has its own flag, diplomatic service, newspaper, railway station, and broadcasting facilities.
