Vatican City officially the State of the Vatican City (Italian: Stato della Città del Vaticano) is a landlocked sovereign city-state whose territory consists of a walled enclave within the city of Rome, the capital city of Italy. It has an area of approximately 44 hectares (110 acres), and a population of just over 800.
Vatican City was established in 1929. It is distinct from the Holy See, which dates back to early Christianity and is the main episcopal see of 1.147 billion Latin and Eastern Catholic adherents around the globe. 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. Very few passports are issued by either authority.
