Why Go

The Cathedral of Rome

Come here for the cathedral of Rome. Saint John Lateran, not Saint Peter's, is the cathedral of the city and the seat of the Pope as Bishop of Rome, and its facade carries the title of the mother and head of all the churches of the City and of the world. It is the oldest of the four major papal basilicas and the first public basilica of Rome, founded by Constantine in the early fourth century. The cathedra in the apse, the papal altar under its medieval baldachin, and the adjoining Constantinian baptistery make this the place where the office of the Bishop of Rome is most clearly read.

From Constantine's Gift to the Cathedral of the Popes

In the early fourth century, after Constantine granted the Church freedom, the first public basilica of Rome was raised on the Lateran estate and dedicated under Pope Sylvester I. It was the cathedral of the Bishop of Rome from the beginning, and the adjoining palace served the popes for about a thousand years. Five ecumenical councils were held here between 1123 and 1517. Fires, earthquake, and rebuilding changed the fabric, but not the identity: this remains the cathedral of Rome.

The Lateran gathers many ages without losing its central axis. Borromini's Baroque nave encloses the older basilica rhythm and leads toward the papal altar, Gothic baldachin, cathedra, and apse mosaic. Beside the basilica, the Cosmatesque cloister and Constantinian baptistery complete the visit as cathedral, not only monument.

Nave Borromini's Nave and the Apostles Borromini reshaped the ancient nave for the Jubilee of 1650, setting the columns within great piers and opening the niches that hold the colossal statues of the Twelve Apostles, carved in the early eighteenth century. Above runs the gilded coffered ceiling. Read the nave toward the papal altar and the apse.

Saint John Lateran is the cathedral of Rome and the seat of the Pope as Bishop of Rome.

It is the oldest major papal basilica and the first public basilica of the city, founded in the Constantinian age.

The cathedra, papal altar, adjoining baptistery, and mother-church title explain the visit more directly than the facade alone.

Spiritual Significance

What gives the Lateran its weight is not its art alone but its office. This is the cathedral of Rome, and the cathedra in its apse is the seat of the Pope as Bishop of Rome. The four other patriarchal and major basilicas, Saint Peter's among them, are great shrines and places of pilgrimage; the Lateran is the cathedral from which the bishop governs his local Church, and through that Church the communion of all the churches. The title written across the facade, mother and head of all the churches of the City and of the world, states the claim plainly. A Catholic visit reads the basilica as the seat of an office: the cathedra, the papal altar reserved to the Pope, the baptistery where the city's faith began, and the long line of councils and popes who have made the Lateran the cathedral of the Church of Rome.

Do Not Miss · 5 stops

Five things, not fifty.

  1. The papal altar and the Gothic baldachin

    At the crossing, the altar reserved to the Pope stands under the Gothic baldachin of 1369, which shelters the reliquary busts venerated by long-standing tradition as the heads of Saints Peter and Paul. This is the liturgical centre of the cathedral.

  2. The papal cathedra

    In the apse stands the cathedra, the seat of the Pope as Bishop of Rome. From this throne the basilica takes its rank as the cathedral of the city and of the world.

  3. The statues of the Apostles

    Walk Borromini's nave under the colossal statues of the Twelve Apostles, carved in the early eighteenth century within the niches he designed for the Jubilee of 1650. Read them as the company that surrounds the cathedra of Peter's successor.

  4. The apse mosaic

    At the head of the basilica, the gold-ground mosaic shows the bust of Christ above the jewelled cross on the hill of paradise, with the rivers of living water. The medieval composition was recomposed when Leo XIII rebuilt the apse.

  5. The Constantinian baptistery

    Beside the basilica stands the baptistery raised under Constantine, the oldest in Christendom and the octagonal model from which baptisteries across the West were built. Reached separately from the basilica.

What to notice
  • That Saint John Lateran, not Saint Peter's, is the cathedral of Rome. The cathedra in the apse is the seat of the Pope as Bishop of Rome, and the title across the facade names the basilica the mother and head of all the churches of the City and of the world.
  • That the basilica is dedicated to Christ the Saviour first, and to Saints John the Baptist and John the Evangelist after; the two titles of Saint John, shared with the adjoining baptistery, are the source of the common name. The facade inscription still reads to Christ the Saviour, in honour of Saints John the Baptist and the Evangelist.
  • How Borromini enclosed the ancient columns of the Constantinian nave in tall white piers for the Jubilee of 1650, opening the niches that the eighteenth century filled with the colossal statues of the Apostles.
  • The Gothic baldachin of 1369 over the papal altar, sheltering the reliquary busts venerated by tradition as the heads of Saints Peter and Paul, and the altar reserved to the Pope beneath it.
  • That the Lateran was the residence of the popes and the seat of the government of the Church for about a thousand years, and that five ecumenical councils were held here between 1123 and 1517.

    4. Santa Croce in Gerusalemme

Saint John Lateran rewards a visit that reads it as the cathedral of Rome rather than as one more basilica. Pause before Galilei's facade and the title of the mother church, then walk Borromini's nave under the statues of the Apostles toward the papal altar and its Gothic baldachin. Pray before the altar and the cathedra in the apse, and read the apse mosaic. Visit the Cosmatesque cloister and the Constantinian baptistery beside the basilica. If time allows, cross the piazza to the Holy Stairs. If a Mass is offered while you are there, join it; the liturgy kept in the cathedral of the Bishop of Rome is itself the reason the basilica exists.

How to Visit

Entering as a pilgrim, not a tourist.

Entry to the basilica is free for prayer year-round. The Cosmatesque cloister is ticketed, and the Constantinian baptistery and the historical complex are reached separately. The Holy Stairs and the Sancta Sanctorum stand in a distinct building across the piazza and keep their own arrangements. Confirm current opening days, ticket arrangements, Mass times, and liturgical schedule on the official basilica site before planning around the visit. The basilica is reached from central Rome by Metro Line A to San Giovanni station, a short walk from the piazza.

  • When to Arrive Mid-morning on a weekday is quietest, before the groups arrive and while the nave reads clearly. The basilica is rarely pressed the way Saint Peter's is, and the wide piazza gives the facade room to be seen.
  • Where to Begin Pause before Galilei's facade, with the colossal statues of Christ and the saints on the balustrade and the title of the mother and head of all churches across the front. Then read Borromini's nave along its single axis toward the papal altar and the apse.
  • Where to Pause Pray before the papal altar under its Gothic baldachin, and before the cathedra in the apse, the seat of the Pope as Bishop of Rome from which the basilica takes its rank as the cathedral of the city and of the world.
  • The Apostles and the Nave Walk the nave slowly beneath the colossal statues of the Twelve Apostles in their niches and the gilded ceiling, and read the apse mosaic at the end with the bust of Christ above the jewelled cross.
  • The Baptistery and Cloister Visit the Constantinian baptistery beside the basilica, the oldest in Christendom, and the medieval Cosmatesque cloister of the canons. Both are reached separately and may be ticketed.
  • The Holy Stairs Nearby Across the piazza, in a separate building, are the Holy Stairs and the old papal chapel of the Sancta Sanctorum. Pilgrims climb the stairs on their knees; the visit is naturally made together with the basilica but is a distinct site.
  • Reverence and Dress Shoulders and knees covered, with reverent dress for the liturgies. Photography is permitted without flash in the basilica, with restrictions during liturgies.
  • Getting There Metro Line A to San Giovanni station leaves a short walk to the basilica. The visit combines naturally with the Holy Stairs, the baptistery, and a walk toward Santa Croce in Gerusalemme.

Connected Saints

How this place gathers the saints.

These saints are connected to the basilica in different ways. The Lateran is dedicated to Christ the Saviour and to Saints John the Baptist and John the Evangelist, whose two titles give the basilica its common name. The reliquary busts above the papal altar are venerated by tradition as the heads of Saints Peter and Paul, whose own tombs lie at the other two apostolic basilicas of Rome, and the basilica was dedicated under Pope Saint Sylvester I.

Editorial sources

Saint John Lateran is the cathedral of the Diocese of Rome and the seat of the Pope as Bishop of Rome, the oldest of the four major papal basilicas, and is honoured as the mother and head of all the churches of the city and the world. The basilica is dedicated to Christ the Saviour and to Saints John the Baptist and John the Evangelist; it should not be presented as a church of a single Saint John. Entry is free for prayer; the cloister, baptistery, and historical complex are ticketed and reached separately. The reliquary busts above the papal altar are venerated by long-standing tradition as the heads of Saints Peter and Paul and are presented here as objects of veneration, not as verified relics. The Holy Stairs and the Sancta Sanctorum across the piazza are a distinct site, kept separate on this page rather than collapsed into the basilica.
