About the Archbasilica of Saint John Lateran
The Archbasilica of Saint John Lateran, also known as the Lateran Basilica, is the cathedral church of the Catholic Diocese of Rome, in Rome, Italy. It is where the bishop of Rome, the pope, has his seat. It is the world's only "archbasilica", and it sits outside Vatican City proper, which is roughly four kilometers to the northwest. Under the Lateran Treaty of 1929, the archbasilica and the buildings next to it, as Holy See property, have extraterritorial status from Italy.
Dating from 324, it is Rome's oldest public church and the oldest basilica anywhere in the Western world. Among the four major papal basilicas it is the oldest, and it is counted among the Seven Pilgrim Churches of Rome. Its name, Laterano, comes from an ancient Roman family whose palace grounds covered the site, and the neighboring Lateran Palace was the pope's main residence until the Middle Ages. Beneath the nave lie substantial remains of a fort for imperial cavalry bodyguards that Septimius Severus set up in AD 193.
The building decayed through the Middle Ages, and two fires in the 14th century badly damaged it. The rebuilding came in the late 16th century, in the reign of Pope Sixtus V, with the architect Domenico Fontana supervising much of the work. Late in the 17th century the interior was renovated, and the façade was finished in 1735 under Pope Clement XII. A large Latin inscription on the façade dedicates the church to Christ the Savior, honoring two saints named John, the Baptist and the Evangelist.
