Archbasilica of Saint John Lateran

The Archbasilica Cathedral of the Most Holy Savior and of Saints John the Baptist and John the Evangelist in the Lateran , also known as the Papal Archbasilica of Saint John [in] Lateran, Saint John Lateran, or the Lateran Basilica, is the cathedral church of the Diocese of Rome in the city of Rome, and serves as the seat of the bishop of Rome, the pope. The archbasilica lies outside of Vatican City proper, which is located approximately 4 kilometres to the northwest. Nevertheless, as properties of the Holy See, the archbasilica and its adjoining edifices enjoy an extraterritorial status from Italy, pursuant to the terms of the Lateran Treaty of 1929.
