Not St Peter's: This Is the Pope's Cathedral

It surprises many travelers, but the cathedral of Rome — the Pope's church in his role as Bishop of Rome — is not St Peter's, it's San Giovanni in Laterano. It is the oldest and highest-ranking of the four papal basilicas, founded by Constantine in the 4th century, which is why it bears the title "Omnium Ecclesiarum Urbis et Orbis Mater et Caput": mother and head of all the churches of the city and the world. A primacy that makes it an unmissable stop — and surprisingly uncrowded compared to the Vatican.

What Makes San Giovanni in Laterano Special

  • The cathedral of Rome: this is where you'll find the cathedra, the throne of the Bishop of Rome (the Pope).
  • The monumental façade by Alessandro Galilei, with colossal statues of Christ and the saints.
  • Borromini's Baroque interior: the nave lined with towering statues of the apostles set in niches.
  • The Cosmatesque cloister: one of the most beautiful in Rome, with its inlaid spiral columns.
  • The Battistero lateranense: the oldest monumental baptistery in the Christian world.
  • The Scala Santa, opposite: the staircase that tradition holds Jesus climbed at Pontius Pilate's palace. → The Scala Santa
  • The Lateran obelisk: the oldest and tallest Egyptian obelisk in Rome, standing in the square.

A Little History

Given by Constantine to the bishop of Rome in the early 4th century, it was the city's first monumental Christian basilica and, for a thousand years, the residence of the popes (the Lateran Patriarchate) before the move to the Vatican. Damaged and rebuilt many times, it owes its present appearance to the work of Borromini (the interior) and Galilei (the façade) in the 17th and 18th centuries.
