About
The Archbasilica of Saint John Lateran is the oldest public place of Christian worship in Western Europe and ranks as the principal cathedral of the Diocese of Rome. Consecrated by Pope Sylvester I in AD 324 under the patronage of Emperor Constantine I, the archbasilica holds the title of 'Mother and Head of all churches in Rome and in the World.'
Rooted in the shared Abrahamic tradition of sacred gathering spaces, the archbasilica represents the liturgical focal point of Catholic unity. It houses the papal throne (cathedra) and serves as the official ecclesiastical seat of the Pope, standing as a primary monument of Latin Christianity.
Throughout seventeen centuries, the basilica has undergone masterwork additions by renowned artists and architects including Domenico Fontana, Francesco Borromini, and Alessandro Galilei. The complex enjoys extraterritorial diplomatic status held by the Holy See under the Lateran Treaty of 1929.
