Vatican City
The name was first used in the Lateran Treaty, signed on 11 February 1929, which established the modern city-state. The name is taken from Vatican Hill, the geographic location of the state. "Vatican" is derived from the name of an Etruscan settlement, "Vatica" or "Vaticum" meaning garden, located in the general area the Romans called "vaticanus ager", "Vatican territory".
List of religious sites
Rome is the place from which Catholics believe the one, holy, catholic and apostolic church were formally founded and begun by St. Peter (whom they consider to be the "Prince of the Apostles") as the appointed successor and first vicar of Christ. Thus while the Holy Sepulchre is still the most sanctified of places for Catholics, the Vatican is an extremely sacred place to the faithful (those of the Latin Church, as well as the Churches "sui iuris") as the seat of their supreme authority on Earth. Important papal territories include the four major basilicas (L.: "Basilica maior", pl. "-es"; excluding St. Peter's) – namely the Archbasilica of St. John Lateran (the ecumenical Catholic mother church), St. Peter's Basilica, the Basilica of St. Paul Outside the Walls (containing the tomb of Paul the Apostle), and the Basilica di Santa Maria Maggiore.
