The Papal Archbasilica of St. John Lateran (Italian: Arcibasilica Papale di San Giovanni in Laterano) is the cathedral of the Church of Rome, Italy, and the official ecclesiastical seat of the Bishop of Rome, who is the Pope. Officially named Archibasilica Sanctissimi Salvatoris et Sancti Iohannes Baptista et Evangelista in Laterano (English: Archbasilica of the Most Holy Saviour and Sts. John the Baptist and the Evangelist at the Lateran", Italian: Arcibasilica del Santissimo Salvatore e Santi Giovanni Battista ed Evangelista in Laterano). It is the oldest and ranks first among the four Papal Basilicas or major basilicas of Rome (having the cathedra of the Bishop of Rome). It claims the title of ecumenical mother church (mother church of the whole inhabited world) among Roman Catholics . An inscription on the façade, Christo Salvatori, indicates the church's dedication to the "Christ the Saviour", for the cathedrals of all patriarchs are dedicated to Christ Himself. As the cathedral of the Bishop of Rome, containing the papal throne (Cathedra Romana), it ranks above all other churches in the Catholic Church, including St. Peter's Basilica in the Vatican. The cathedral itself is located outside of the Vatican City boundaries, territorially located within the city of Rome in the Italian Republic. However it has been granted a special extraterritorial status as a property of the Holy See. This is also the case with several other buildings after the solving of the Roman Question with the Lateran Treaty. ( Wikipedia The Free Encyclopedia )
