Papado de Aviñón
Before the Avignon Papacy (1305–1378), the headquarters of the Holy See were located at the Lateran Palace. After the Avignon Papacy the church administration moved to Vatican Hill and the papal palace was (until 1871) the Quirinal Palace, upon the Quirinal Hill. Since June 1929, part of the Vatican Hill is the site of the State of the Vatican City. However, the cathedral of the Bishop of Rome, the Pope, is not St. Peter's in the Vatican, but Basilica di San Giovanni in Laterano, which is extra-territorially linked, as indicated in the Lateran Pacts signed with the Italian state in February 1929, with the Holy See.
