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.
Entering as a pilgrim, not a tourist.
-
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.
Five things, not fifty.
-
01
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.
-
02
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.
-
03
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.
-
04
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.
-
05
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.

Half day Pilgrims reading the Lateran complex
The Lateran with the Holy Stairs
Add the Holy Stairs and the Sancta Sanctorum across the piazza, and a walk toward Santa Croce in Gerusalemme among the relics of the Passion.
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.
From Constantine's Gift to the Cathedral of the Popes
When the Emperor Constantine granted the Church its freedom, he gave to the Bishop of Rome the land of the Laterani family on the south-eastern hills of the city, and there, in the early fourth century, the first public basilica of Rome was raised and dedicated under Pope Sylvester I. It was the cathedral of the Bishop of Rome from the beginning, and the adjoining palace was the residence of the popes and the centre of the government of the Church for about a thousand years, until the popes returned from Avignon and settled at last by the Vatican. Five ecumenical councils were held at the Lateran between 1123 and 1517. The basilica was dedicated first to Christ the Saviour; the titles of Saint John the Baptist and Saint John the Evangelist were added in connection with the adjoining baptistery and the monastic community that served it, and from them the basilica takes its common name. The building suffered through the centuries, sacked, shaken by earthquake, and twice burned during the Avignon years, and was rebuilt each time. For the Jubilee of 1650, Pope Innocent X entrusted the nave to Francesco Borromini, who clothed the ancient columns in great piers and opened the niches that would later hold the colossal statues of the Apostles. The east facade, with its colossal statues of Christ and the saints, was completed by Alessandro Galilei in 1735 under Clement XII. At the end of the nineteenth century Pope Leo XIII rebuilt and lengthened the apse, recomposing its medieval mosaic, and chose to be buried there. Through every rebuilding the basilica has remained what it was at the beginning: the cathedral of Rome and the seat of its bishop.
The Lateran gathers many ages in one building. Beneath the Baroque surface lies the plan of the Constantinian basilica, the first great public church of Rome. Borromini's remodelling of 1646 to 1650 gave the nave its present rhythm, enclosing the ancient columns in tall white piers and framing the niches that hold the eighteenth-century statues of the Twelve Apostles. Over the crossing rises the Gothic baldachin of 1369, the canopy over the papal altar and the reliquary busts of the Apostles. The apse, rebuilt under Leo XIII, carries the recomposed medieval mosaic of Christ and the jewelled cross. Beside the basilica stand the medieval Cosmatesque cloister of the canons, completed by the Vassalletto family in the early thirteenth century, and the Constantinian baptistery, the oldest in Christendom and the model of baptisteries across the West. Galilei's facade of 1735 gives the whole complex its great east front on the piazza.
A place is significant when it is still used.
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.
- 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.
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. The label on each card names how that connection is held.

The Lateran Baptistery
Constantinian baptistery
Raised under Constantine beside the basilica, the octagonal baptistery is the oldest in Christendom and the model from which baptisteries across the West were built. Reached separately from the basilica.
-
The Holy Stairs and Sancta Sanctorum
Pilgrim shrine
Across the piazza in a separate building, the Holy Stairs are climbed by pilgrims on their knees, leading to the Sancta Sanctorum, the old private chapel of the popes. A distinct site, naturally visited with the basilica.

Santa Croce in Gerusalemme
Basilica of the Passion relics
One of the seven traditional pilgrim churches of Rome, raised by Saint Helena to enshrine the relics of the Passion she is said to have brought from Jerusalem. A natural continuation of a Lateran pilgrimage.
-
Basilica of Santa Maria Maggiore
Papal basilica
The great Marian basilica of Rome, read with Saint John Lateran along the spine of the papal basilicas. About twenty-five minutes by Metro Line A and a short walk.
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.
