Outline of Vatican City
Vatican City – an ecclesiastical or sacerdotal-monarchical state, being the sovereign territory of the Holy See and ruled by the Bishop of Rome—the Pope, the leader of the worldwide Catholic Church. The territory of this landlocked sovereign city-state consists of a walled enclave within the city of Rome, Italy. It has an area of approximately , and a population of just over 800. This makes Vatican City the smallest independent state in the world by both area and population.Geography of Vatican CityVatican City is an enclave in an urban area, and lacks the geographic features common to (much larger) countries:Demographics of Vatican City
Vatican City
The name "Vatican" predates Christianity and comes from the Latin "", meaning Vatican Mount. The territory of Vatican City is part of the "Mons Vaticanus", 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 various other buildings. The area was part of the Roman "rione" of Borgo until 1929. Being separated from the city, on the west bank of the river Tiber, the area was an outcrop of the city 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. For some tracts of the frontier, there was no wall, but the line of certain buildings supplied part of the boundary, and for a small part of the frontier a modern wall was constructed.
