St. John's Church, Lateran Palace, Rome
The Basilica of St. John Lateran (Italian: Basilica di San Giovanni in Laterano) is the cathedral of the church of Rome and the official ecclesiastical seat of the Bishop of Rome, who is the Pope. As the cathedral of the Bishop of Rome, containing the papal throne (Cathedra Romana), it ranks above all other churches in the Roman Catholic Church, even above St. Peter's Basilica in the Vatican.
