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
Archbasilica of St. John Lateran
When the papacy returned from Avignon and the pope again resided in Rome, the archbasilica and the Lateran Palace were deemed inadequate considering their accumulated damage. The popes resided at the Basilica di Santa Maria in Trastevere and later at the Basilica di Santa Maria Maggiore. Eventually, the Palace of the Vatican was built adjacent to the Basilica of St. Peter, which existed since the time of Emperor Constantine I, and the popes began to reside there. It has remained the official residence of the pope (though Pope Francis unofficially resides elsewhere in the Vatican City).
