The Lateran Palace, formally the Apostolic Palace of the Lateran, is an ancient palace of the Roman Empire and later the main papal residence in Rome.
Located on St. John's Square in Lateran on the Caelian Hill, the palace is adjacent to the Archbasilica of Saint John Lateran, the cathedral church of Rome. The wealthy Lateran family held the palace estate during the Roman Empire, and the estate eventually came into the hands of the Emperor Constantine. From the fourth century, the palace was the principal residence of the popes, and continued so for about a thousand years until the Apostolic Residence ultimately moved to the nearby Vatican.
