Santa Maria Maggiore

Two things make this basilica extraordinary, and most visitors now come for the second. The first is that it still has the shape and the mosaics it was given in the 430s — alone among Rome's four papal basilicas, it was never rebuilt out of existence. The second is a plain white slab in the left aisle with one word on it, cut in 2025, which made this the first church outside the Vatican to bury a pope in over a century. This guide walks the building object by object, and is honest about which of its famous stories are documented and which are not.

Snow in August, and a council in Ephesus

The legend

The story is that a Roman patrician and his wife both dreamed on the same night that the Virgin wanted a church built wherever snow fell the next morning — and on 5 August, in the middle of a Roman summer, snow fell on the summit of the Esquiline. Pope Liberius is said to have traced the outline of the building in the drift himself.

It is a wonderful story and it is almost certainly not what happened. The tradition dates the miracle to 358 and the building on this spot to Liberius; the basilica you walk into was raised about eighty years later under a different pope. The church has never stopped telling the story — see the 5 August ceremony below — and it is worth knowing it as legend rather than founding record.

What actually happened

The real building went up between 432 and 440 under Sixtus III, immediately after the Council of Ephesus of 431 had settled a fierce argument by declaring Mary Theotokos, God-bearer. That is the key to the whole interior. This is not a church that happens to be dedicated to Mary; it is a church built as an argument about her, at the moment the argument was won, and the mosaics are the case being made.

It is one of Rome's four papal basilicas, with St Peter's, St John Lateran and St Paul Outside the Walls. Alone among them it has kept its fifth-century footprint, its nave colonnade and much of its original decoration under everything added since. The others were rebuilt, burned, or rebuilt again.

The visitor's cheat sheet

What to see, in the order you meet it

The piazza, the column and the obelisk

The single fluted column standing in front of the basilica is the last survivor of the eight that held up the Basilica of Maxentius in the Forum. Paul V had Carlo Maderno move it here in 1614 and put a bronze Virgin and Child on top — a pagan imperial column repurposed, quite deliberately, as a Marian monument.

Walk round the back for the second one. The obelisk behind the apse is Roman rather than Egyptian-inscribed: one of a pair that flanked the entrance to the Mausoleum of Augustus, its twin now standing behind the Quirinal. Domenico Fontana re-erected it here in 1587 for Sixtus V as a waymark in his replanning of the city — part of a scheme of obelisks placed so that pilgrims could see the next basilica from the last.

The facade, the loggia and the mosaic inside it

The front is Ferdinando Fuga's, of 1743–50, with four marble angels by Pietro Bracci, and it is doing something unusual: it is a glass case. Behind the loggia arches, protected from the weather, survives the late-thirteenth-century facade mosaic by Filippo Rusuti — Christ enthroned above, the snow miracle below. Fuga built a new front without destroying the old one, and the only way to see Rusuti's work properly is to take the museum ticket that includes the loggia.

The campanile

Round the side, the brick Romanesque bell tower, rebuilt in 1370–78 under Gregory XI at 75 metres. That makes it the tallest campanile in Rome, which is a real and uncontested record — a bell-tower record, not a building one; the dome of St Peter's is nearly twice its height.

The nave

Inside, the surprise is how ancient the shape is. Forty columns of Athenian marble, mostly reused from Roman buildings, march down both sides under a straight architrave rather than arches — the classical basilica plan, not the medieval one. Fuga regularised them in the 1740s and walled some into piers, but the proportions are the fifth century's.

The nave mosaics

Above the architrave, in panels most visitors never look up at, is the oldest surviving cycle of biblical narrative mosaics in Rome: Abraham, Isaac and Jacob down the left wall, Moses and Joshua down the right, made 432–440. They are Old Testament scenes in a church about Mary, because the argument being made is one of typology: these are the events that prefigure what the triumphal arch is about to show you.

How many survive is genuinely disputed. Sources give 27, 36 or 42; the likeliest reading is that there were 42 originally and that between a quarter and a third were lost when the Sistine and Pauline chapels were cut through the aisles. Take a pair of binoculars: they are small, they are high, and the lighting does not help.

The triumphal arch

The arch over the sanctuary is the same date and the same argument at full volume. At the apex is the Hetoimasia, the empty jewelled throne prepared for Christ's return. Around it run the scenes of his infancy — Annunciation, Adoration of the Magi, Presentation, the Massacre of the Innocents — with Jerusalem and Bethlehem as jewelled cities below.

Look at how Mary is dressed. She is not a peasant girl in blue. She is in the pearls and gold of a Roman empress, enthroned, attended. That is the Council of Ephesus, translated into fifth-century political imagery, within a decade of the decision.

The apse mosaic

The apse is eight hundred years younger and just as good. Nicholas IV had the old apse pulled down and rebuilt further back in 1288–92, and Jacopo Torriti filled the new one in 1295 with the Coronation of the Virgin: Christ and his mother enthroned side by side, in a disc of stars, with rivers, peacocks and vine scrolls below. He signed it.

Enthroning the two of them together, at equal height, was a bold composition and it was widely copied afterwards. It has been restored, notably in the nineteenth century, but unlike the apse at the Lateran this is Torriti's own mosaic rather than a Victorian copy of one.

The ceiling, and the gold that probably wasn't

The flat gilded coffered ceiling was begun under Callixtus III in 1455 and finished under Alexander VI, and is traditionally attributed to Giuliano da Sangallo with his father Francesco — traditionally, meaning it is not documented.

Every guide will tell you it was gilded with the first gold Columbus brought back from the Americas, presented to the Spanish pope by Ferdinand and Isabella. There is no contemporary record of it, and the chronology is awkward, since the ceiling was begun in 1455 and Columbus sailed in 1492. It is a lovely story about a Borgia pope and it belongs in the same category as the snow: worth telling, not worth asserting.

The floor

Look down. The Cosmatesque pavement was laid around 1145–53 under Eugene III and paid for by a father and son, Scoto Paparoni and Giovanni, who are named in an inscription in it. Donor inscriptions in floors are rarer than you would think, and this one is a reminder that most of what you are walking on in Rome was somebody's specific gift, recorded at the time.

The confessio and the Holy Crib

In front of the high altar, steps go down to the confessio, rebuilt by Vespignani in 1864, with a kneeling statue of Pius IX by Jacometti at the bottom. In the crypt beneath — the Bethlehem Crypt — is a rock-crystal and silver-gilt reliquary made by Giuseppe Valadier in 1802, holding five slats of wood venerated as pieces of the manger.

On its date, the honest answer is that nobody has published one. There has never been a radiocarbon test. A seventeenth-century examination identified the wood as sycamore, which is at least consistent with the Levant, and Origen records a crib being venerated at Bethlehem around 220. The wood is traditionally carried up into the basilica only for Midnight Mass at Christmas.

Salus Populi Romani

On the altar of the Pauline Chapel, in the left transept, is the icon that explains everything about this basilica's last decade. Salus Populi Romani — Health, or Salvation, of the Roman People — is a painting of the Virgin and Child on cedar panel, about 117 by 79 centimetres, which tradition says was painted by St Luke on the table of the Holy Family.

The Vatican Museums, who restored it and unveiled the result in 2018, put it rather differently: the dating, “although controversial, would seem to be between the ninth and twelfth centuries”. The restoration removed nineteenth-century overpaint and a metal cover, and the face that came out from under it is far better than the one generations had been looking at. It is carried through Rome in times of plague and crisis, and it is the icon Pope Francis prayed before and after every journey of his papacy.

The Pauline Chapel

The chapel round it was built to house it: Flaminio Ponzio's, 1605–11, for Paul V, with frescoes by Guido Reni, Cigoli and others, and the tombs of Paul V and Clement VIII facing each other. It is one of the most lavish chapels in Rome and it is frequently railed off, so look from the transept rather than assuming you can walk in.

The tomb of Pope Francis

Between the Pauline Chapel and the Sforza Chapel, in a plain niche in the left aisle, is a slab of Ligurian marble — chosen because his mother's family came from Genoa — with one word on it: FRANCISCUS. Above it hangs a reproduction of his pectoral cross. There is nothing else. No effigy, no coat of arms, no Latin inscription of titles.

He was buried here on 26 April 2025, the first pope interred outside the Vatican since Leo XIII in 1903, and he requested it in writing as early as 2023. In the first days after the funeral more than thirty thousand people a day filed past; it has settled since into a steady queue, free and unticketed, managed one-way by stewards. Whatever you make of the man, the restraint of the thing is remarkable in a city whose churches are wallpapered with papal self-commemoration.

Bernini's slab

And a few metres away, in the floor near the high altar by the entrance to the Sistine Chapel, is a stone almost everybody walks over. It reads Nobilis familia Bernini hic resurrectionem expectat — the noble Bernini family awaits the resurrection here. Gian Lorenzo Bernini, who designed more spectacular tombs than any sculptor in history, is under a plain slab with no portrait and no monument. It is the best joke in Rome and it is entirely unmarked.

The Sistine Chapel of Sixtus V

Right transept, and worth the confusion. Domenico Fontana built it in 1585–90 as a setting for the Blessed Sacrament and for its patron's tomb; Sixtus V and St Pius V are both buried in it, facing each other. Fontana's real feat was engineering: he moved the entire medieval Bethlehem oratory, in one piece, on rollers, to sit underneath the new chapel. The same man moved the Vatican obelisk. Look up into the dome.

The snowfall, every 5 August

The basilica has never let the legend go, and the way it marks it is genuinely worth planning around. On the Solemnity of Our Lady of the Snows, 5 August, there is a solemn Mass at 10am during which white rose petals are released from a coffer in the nave ceiling and fall through the basilica during the Gloria; a second fall comes at Second Vespers at 5pm, during the Magnificat. It is free and unticketed, first come until the building is full, and a triduum of preparation runs from 2 August.

One correction worth making: the petals fall inside. Several blogs describe an outdoor light-projection snow show in the piazza; that is not part of the official programme.

Insider tips

Bring binoculars or a long lens. This is the single most under-equipped visit in Rome: the mosaics that make the basilica important are twelve metres up and small, and almost nobody can actually see them.

Check the museum hours on the day rather than in advance. The basilica's own site and the city tourist board publish different opening times for the same museum complex, and neither publishes a price until you start booking.

It is five minutes from Termini, which makes it the best thing in Rome to do with a spare hour before a train — and one of the few major basilicas where you can walk in free, at eight in the morning, with almost nobody there.

Where to stay and eat nearby

The Esquiline around the basilica is a working quarter rather than a sightseeing one, and the streets immediately by Termini are the least appealing part of central Rome. Walk ten minutes towards Monti — the neighbourhood between here and the Colosseum — for the best eating and the nicest small hotels in this half of the city.
