Neighborhood: Borgo / Vatican

The pilgrim quarter at the basilica's feet

🧭 Why Visit

The largest church in Christendom, built over the apostle's grave, crowned by Michelangelo's dome, and home to his Pietà, carved at 24. Free to enter, impossible to forget, best at 7 AM before the crowds.

🏛️ A Little History

Constantine raised the first basilica here around 320 AD over Peter's burial site; the current one took 120 years (1506–1626) and every great name of the Renaissance and Baroque, Bramante, Michelangelo, Bernini, to complete.

💡 Did You Know?

The marks on the nave floor show where other great cathedrals would end if placed inside. St. Paul's London falls 40 meters short. Excavations in the 1940s found bones beneath the altar consistent with a first-century man; the Church declared them Peter's.

THE APPROACH

St. Peter's Square

Bernini's colonnade gathers the whole city toward the doors.

St. Peter's Square and Bernini's colonnade under a dramatic cloudy sky
St. Peter's SquareBernini wrapped the piazza in two great colonnades of 284 columns, closing around the obelisk so the church could gather the whole city into its embrace. Storm light gives the travertine an edge.
Rows of chairs set out in St. Peter's Square before the obelisk and facade
Before an AudienceRows of chairs fill the square ahead of a papal audience, the obelisk and facade beyond. On an ordinary morning it is empty stone; on these days it holds tens of thousands.
St. Peter's Square seen from the shade of the basilica portico
From the PorticoStep out of the shade of the entrance and the square opens all at once. The colonnade runs off to both sides and the city waits beyond the far end.
AT THE THRESHOLD

The Facade and the Doors

The front of the church, and the bronze doors that have opened for centuries.

The travertine facade of St. Peter's Basilica with its rooftop statues
The FacadeCarlo Maderno's front is wider than a football field and carries a row of colossal statues along the top. From the square you crane your neck, and the scale never quite fits in the frame.
The colossal columns of St. Peter's facade seen from below against clouds
Under the FacadeMaderno's colossal columns close overhead as you reach the steps, each one far taller than it looks from across the square. The clouds do the rest.
The bronze gilded Holy Door of St. Peter's Basilica with relief panels
The Holy DoorThe Porta Santa is bricked shut on the inside and opened only in a Jubilee year, then sealed again until the next. It last stood open from Christmas 2024 to the start of 2026.
Filarete's fifteenth-century bronze central doors of St. Peter's Basilica
The Central DoorsFilarete cast these bronze doors in the 1440s for the old basilica, and they were carried over into the new one. Saints, emperors and martyrdoms crowd every panel.
The gilded stucco vault of the entrance portico of St. Peter's
The Portico VaultBefore you reach the doors you pass under this, a gilded stucco ceiling running the full width of the front. It is easy to walk straight past on the way in.
The long marble entrance portico of St. Peter's Basilica
Along the PorticoThe entrance hall stretches the whole width of the church, marble underfoot and light falling in from the square at one end.
A Pontifical Swiss Guard in striped uniform standing with a halberd
The Swiss GuardThe Pope's guard has come from Switzerland since 1506, and the striped uniform is still cut the old way. One stands watch here with the ceremonial halberd.
THE GREAT NAVE

Into the Basilica

The longest nave in the world, and the floor that measures it.

The nave of St. Peter's looking toward Bernini's baldachin under the dome
The Length of the NaveThe floor runs the length of nearly two football fields to Bernini's bronze canopy, and even a full church looks sparse inside it. This is the largest church interior in the world.
The gilded coffered barrel vault of the nave of St. Peter's Basilica
The Coffered VaultGold and white coffering runs the whole barrel of the ceiling, each sunken panel deeper than it looks from the floor. Turn back toward the doors and it carries your eye all the way out.
The crossing of St. Peter's looking up to the dome drum and its inscription
Tu Es PetrusLetters two metres tall ring the base of the dome: you are Peter, and on this rock I will build my church. From the floor they look an ordinary size.
The round porphyry disc set into the marble floor of St. Peter's Basilica
The Porphyry DiscThis round slab of purple porphyry sat before the altar of the old basilica for centuries. Charlemagne is said to have knelt on it to be crowned emperor on Christmas Day of the year 800.
AT TWENTY-FOUR

Michelangelo's Pietà

The young sculptor's only signed work, carved from a single block.

Michelangelo's Pieta lit by a shaft of window light, St. Peter's Basilica
The PietàMichelangelo carved Mary and her son from a single block of Carrara marble before he was twenty-five. It is the only work he ever signed, on the sash across her breast.
Close view of Michelangelo's Pieta behind protective glass in St. Peter's
A Single BlockThe folds of cloth, the veins in Christ's hand, the young face of the mother, all of it came out of one piece of stone. Since a 1972 attack it sits behind glass, so this is about as close as anyone gets.
The face of the Virgin Mary in Michelangelo's Pieta, looking downward
Her FaceMichelangelo made the mother look younger than her son and defended it: purity, he said, keeps a face from aging. She looks down rather than out, her grief turned inward.
OVER THE TOMB OF PETER

Bernini's Baldachin and the Crossing

The bronze canopy, the great statues, and the Chair of St. Peter.

Bernini's twisted-column bronze baldachin over the papal altar of St. Peter's
Bernini's BaldachinThe bronze canopy stands as tall as an eight-storey building over the papal altar, its spiral columns twisting up toward the dome. Bernini spent eleven years on it, and some of the bronze is said to have come from the Pantheon.
Bernini's baldachin glowing beneath the dome of St. Peter's Basilica
Beneath the DomeUnder the crossing the baldachin glows against the gold, its spiral columns climbing toward the ring of the dome. The single lamp marks the tomb of Peter below.
Bernini's gilded Chair of St. Peter and the dove window in the apse
The Chair of St. PeterBeyond the altar, Bernini set an ancient wooden chair inside a burst of gilded bronze and cloud. The amber window at its heart shows the dove of the Holy Spirit.
Bernini's marble statue of St. Longinus with outstretched arms, St. Peter's
St. LonginusBernini carved the soldier who pierced Christ's side, caught at the moment of belief with his arms flung open. He is one of four giants set into the piers under the dome.
The medieval bronze statue of St. Peter enthroned, its foot worn smooth
The Bronze St. PeterPilgrims have touched and kissed the right foot of this seated bronze for so long that the toes have worn smooth. The statue is medieval, older than almost everything around it.
SIDE BY SIDE WITH SAINTS

Chapels, Altars and Papal Tombs

Mosaic altarpieces and the tombs of popes and a queen along the aisles.

Mosaic copy of Raphael's Transfiguration above an altar in St. Peter's
The TransfigurationRaphael's last painting hangs here as a mosaic so fine it is hard to believe it is not paint. Almost every altarpiece in the basilica is mosaic, made to outlast the damp that would ruin canvas.
A tall mosaic altarpiece in a side chapel of St. Peter's Basilica
A Towering AltarpieceThe side altars rise the full height of the aisle, their paintings reproduced in mosaic so fine it passes for brushwork. The Vatican kept a studio running for centuries to make them.
The monument to Queen Christina of Sweden in St. Peter's Basilica
Queen Christina of SwedenChristina gave up the Swedish throne in 1654, converted to Catholicism and moved to Rome, where she became a great patron of the arts. Carlo Fontana's monument marks one of the very few women honoured in the basilica.
The monument to Pope Benedict XIII in St. Peter's Basilica
Pope Benedict XIIIA Dominican friar who stayed one at heart, Benedict XIII kept a monk's simple life through his papacy in the 1720s. His monument stands among the popes along the aisle.
The tomb of St. John Paul II, a marble slab with a gilded cross
St. John Paul IIA plain marble slab and a gilded cross mark where John Paul II lies, near the chapel of St. Sebastian. It is one of the most visited spots in the church, and usually one of the quietest.
The glass tomb of St. John XXIII beneath the Altar of St. Jerome, St. Peter's
St. John XXIIIGood Pope John, who opened the Second Vatican Council, lies in a glass casket beneath the Altar of St. Jerome. His body has been on view here since 2001, and he was made a saint in 2014.
The porphyry baptismal font with gilded cover in St. Peter's Basilica
The BaptisteryThe font is a great basin of porphyry topped with a gilded bronze cover. Children of the parish of St. Peter's are still baptised here.
MICHELANGELO'S CROWN

Under the Dome

The dome from directly below, rising to the lantern.

The interior of Michelangelo's dome seen from directly below, St. Peter's
Michelangelo's DomeLooking straight up, the dome rises some 120 metres to the lantern, ringed with mosaic saints and windows. Michelangelo designed it but never lived to see it finished.
The coffered interior of the dome of St. Peter's rising to the lantern
Up to the LightBands of gold coffering climb toward the small opening at the very top, where daylight falls through the lantern. It is the model half the domes in the world are copied from.
A colossal mosaic figure in a pendentive of the dome of St. Peter's Basilica
Into the PendentivesWhere the dome settles onto its four piers, colossal mosaic figures fill the curved corners, each far larger than they read from the floor. The dome inscription carries on around them.
551 STEPS UP

The Dome Climb

Rome, the gardens, and the square laid out from the top.

St. Peter's Square and colonnade seen from the top of the dome
The Square from the TopFrom the lantern the whole plan makes sense: two arms of colonnade closing around the obelisk, the city pressing up to the edge of the Vatican. The climb is 551 steps, and this is the reward.
View from the dome over the colonnade and St. Peter's Square in summer
Over the ColonnadeThe roofline of the colonnade carries its own crowd of statues, saints looking out over the square they help enclose. Summer haze softens the city beyond.
The exterior shell of Michelangelo's dome from the terrace, Rome beyond
The Dome Up CloseOut on the terrace the dome fills the sky, its ribs of travertine climbing to the lantern while Rome spreads out below. You are standing on the roof of the largest church on earth.
The Vatican Governor's Palace and its heraldic garden from the dome
The Governor's PalaceSeen from above, the palace of the Vatican governorate keeps a formal garden laid out in the shape of a coat of arms. Few visitors ever walk here.
The wooded Vatican Gardens behind St. Peter's seen from the dome
The Vatican GardensHalf of the Vatican is green. The gardens climb the hill behind the basilica, fountains and umbrella pines threading through the trees, and from this height the crowds vanish.
Looking down the stone ribs of St. Peter's dome toward the Vatican Gardens
Down the RibsThe outer shell of the dome falls away in stone ribs toward the gardens far below. There is a real drop here, and the view earns every one of the steps.
AFTER DARK

St. Peter's by Night

The basilica floodlit after the crowds have gone.

The floodlit facade, dome and obelisk of St. Peter's at night
St. Peter's After DarkLate in the evening the crowds thin, the floodlights come up, and the facade, dome and obelisk stand alone over the wet stone. The square is at its most beautiful when almost no one is there to see it.
The illuminated dome and obelisk of St. Peter's Basilica at night
The Dome at NightMichelangelo's dome glows above the loggia, the obelisk a dark needle against the light. It is close to the view a pilgrim would have had by torchlight for four hundred years.
St. Peter's Basilica floodlit at night above an empty square
Empty SquareThe lamps of the colonnade trail off into the dark and the whole square belongs to a handful of late walkers. Worth staying in Rome an extra evening for.

Frequently Asked Questions

Is St. Peter's Basilica really free?
Yes, entry to the basilica is completely free. You only pay for optional extras: dome climb (€10 with elevator, €8 stairs only), audioguide (€5), or guided tours. The Vatican Grottoes with papal tombs are also free.
Is climbing the dome worth it?
Absolutely - it's Rome's best view. Take elevator to terrace level (€10) then climb 320 steps. The final section is narrow and claustrophobic - not for those with mobility issues or claustrophobia. Go early morning for shortest lines.
How do I skip the security lines?
Book a guided tour that includes skip-the-line access, or enter through Vatican Museums (with Sistine Chapel tour). Morning tours before 9 AM have shortest waits. Free entry always requires security screening.
Can I see the Pope?
Wednesday Papal Audiences (10:30 AM) are free but require tickets from Vatican website. Sunday Angelus (noon) from apartment window needs no ticket - arrive by 11 AM for good spot in square. Check Vatican calendar for schedule.
Can I photograph the Pietà?
Yes, photography is allowed throughout the basilica (no flash). The Pietà is behind bulletproof glass since 1972 attack. Best photos from the right side. The dome interior offers spectacular photo opportunities.
What's in the Treasury?
The Basilica Treasury (€5 entry) contains papal artifacts, jeweled crosses, and vestments. Honestly skippable unless you're deeply interested in Catholic artifacts. Time better spent climbing dome or visiting grottoes.
