Vatican

The name Vatican City was first used in the Lateran Treaty, signed on 11 February 1929, which established the modern city-state named after Vatican Hill, the geographic location of the state within the city of Rome. Vatican itself is derived from the name of an Etruscan settlement, Vatica or Vaticum, located in the general area the Romans called Ager Vaticanus ('Vatican territory'). The Italian-language name of the city is Città del Vaticano or, more formally, Stato della Città del Vaticano, meaning 'State of Vatican City'. Its Latin name is Status Civitatis Vaticanae; this is used in official documents by the Holy See, the Church and the pope.

The name "Vatican" was already in use in the time of the Roman Republic for the Ager Vaticanus, a marshy area on the west bank of the Tiber across from the city of Rome, located between the Janiculum, the Vatican Hill and Monte Mario, down to the Aventine Hill and up to the confluence of the Cremera creek. The toponym Ager Vaticanus is attested until the 1st century AD: afterwards, another toponym appeared, Vaticanus, denoting an area much more restricted: the Vatican Hill, today's St. Peter's Square, and possibly today's Via della Conciliazione. Because of its vicinity to Rome's archenemy, the Etruscan city of Veii (another naming for the Ager Vaticanus was Ripa Veientana or Ripa Etrusca), and for being subjected to the floods of the Tiber, the Romans considered this originally uninhabited part of Rome dismal and ominous. …

The territory of Vatican City is part of the Vatican Hill, and of the adjacent former Vatican Fields. It is in this territory that St Peter's Basilica, the Apostolic Palace, the Sistine Chapel, and museums were built, along with other buildings. The area was part of the Roman rione of Borgo until 1929. Being separated from Rome, on the west bank of the river Tiber, the area was an outcrop of Rome that was protected by being included within the walls of Leo IV (847–855), and later expanded by the current fortification walls, built under Paul III (1534–1549), Pius IV (1559–1565), and Urban VIII (1623–1644). When the Lateran Treaty of 1929 that gave the state its form was being prepared, the boundaries of the proposed territory were influenced by the fact that much of it was all but enclosed by this loop. …

The Vatican City is home to some of the most famous art in the world. St Peter's Basilica, designed by a succession of architects including Bramante, Michelangelo, Giacomo della Porta, Carlo Maderno and Gian Lorenzo Bernini, is a renowned work of Renaissance architecture. The Sistine Chapel is famous for its frescos, which include works by Perugino, Domenico Ghirlandaio and Sandro Botticelli, as well as the ceiling and Last Judgment by Michelangelo. The interiors of the Vatican were decorated by artists including Raphael and Fra Angelico. The Vatican Apostolic Library and the collections of the Vatican Museums are of the highest historical, scientific and cultural importance. Added by UNESCO to the List of World Heritage Sites in 1984, the Vatican is the only site to consist of an entire state. …

The Vatican City State budget includes the Vatican Museums and post office and is supported financially by the sale of stamps, coins, medals and tourist mementos; by fees for admission to museums; and by publications sales. The incomes and living standards of lay workers are comparable to those of counterparts who work in the city of Rome. Other industries include printing, the production of mosaics, and the manufacture of staff uniforms. The Institute for Works of Religion (IOR, Istituto per le Opere di Religione), also known as the Vatican Bank, is a financial agency situated in the Vatican that conducts worldwide financial activities. It has multilingual ATMs with instructions in Latin, possibly the only ATM in the world with this feature. Vatican City issues its own coins and stamps. …
