VATICAN CITY – The Holy See
Vatican City, officially the State of the Vatican City is a landlocked sovereign city-state whose territory consists of a walled enclave within the city of Rome. At approximately 44 hectares (110 acres), and with a population of around 900, it is the smallest state in the world by both population and area.
The Vatican City is a city-state that came into existence in 1929 and is thus clearly distinct from the central authority of the Roman Catholic Church, known as the Holy See, which existed long before 1929. Ordinances of Vatican City are published in Italian. Official documents of the Holy See are issued mainly in Latin. The two entities even have distinct passports: the Holy See, not being a country, only issues diplomatic and service passports; the state of Vatican City issues normal passports. In both cases the number of passports issued is extremely limited.
