St. Peter's Basilica
Basilica Sancti Petri
The largest church on Earth, raised over the tomb of Saint Peter and capped by Michelangelo's dome.
- UNESCO World Heritage (Vatican City, 1984)
St Peter's Basilica in Vatican City is the largest church in the world, 186 metres long, built between 1506 and 1626 over the traditional burial site of the apostle Peter. Its dome, designed by Michelangelo, rises 136 metres and remains the tallest in the world.
The Place
The basilica runs 186 metres from door to apse & markers set into the marble floor of the nave show where the great cathedrals of the world would end if laid out inside it, each falling well short. Overhead, Michelangelo's dome climbs 136 metres to the top of its cross, still the tallest in the world. Beneath it, Bernini's bronze baldachin rises nearly 30 metres over the high altar on twisted columns cast from metal stripped from the Pantheon's portico. Near the entrance, behind glass since a 1972 hammer attack, stands Michelangelo's Pieta, carved when he was in his early twenties.
Why It Matters
This is the ceremonial centre of the Roman Catholic Church, where the pope leads the largest liturgies and where his death and election play out before the world. Its authority rests on what lies beneath the dome: the tomb traditionally held to be that of Saint Peter, the apostle Catholics count as the first pope. Excavations under the basilica in the twentieth century uncovered an ancient burial ground and a grave at precisely the spot where tradition had always placed it, directly below the high altar.
The Story
An earlier basilica, built by the emperor Constantine in the fourth century, stood here for over a thousand years before it was judged beyond saving. Pope Julius II ordered it torn down and replaced & the new St Peter's rose between 1506 and 1626 under a relay of architects: Bramante began it, Raphael took a turn, Michelangelo designed the dome in his seventies & Carlo Maderno added the long nave and facade. To raise the money, the Church sold indulgences, the practice that pushed Martin Luther to write his theses in 1517 and helped ignite the Reformation.
Being There
The interior defeats the eye's sense of scale. Cherubs holding holy-water basins near the door look ordinary until you stand beside one and find it taller than a person. The lettering of the inscription running around the base of the dome is two metres high, though from the floor it reads as normal text. For those willing to climb, 551 steps lead up through the curve of the dome itself, the walls tilting inward as you go, to a gallery on the lantern with the whole of Rome spread below.
Knowing Before You Go
Entry to the basilica is free, but the security line crossing St Peter's Square can take well over an hour at midday & a strict dress code bars bare shoulders and knees. The dome climb is a separate paid ticket, with the option to take a lift for the first stretch and the stairs for the rest. Going early, soon after the morning opening, beats both the heat and the worst of the crowds.

Heritage · Unesco Cultural · Cupola di San Pietro A dome shaped by five architects across a century, engineered to carry its own enormous weight without spreading apart.
What You're Looking At
From outside, the dome sits on a tall drum ringed by paired Corinthian columns, sixteen of them, each 15 metres high, with sixteen stone ribs running up to the lantern. Inside, the coffered ceiling draws the eye upward toward mosaics far overhead. The shape is not a plain hemisphere: it rises to a slightly pointed, ovoid profile, a choice that changes how the structure behaves under its own weight and how it reads against the Roman skyline from a distance.
The Story
The dome's design took over a century to settle. Donato Bramante proposed the first scheme in 1506, taking cues from the Pantheon & Raphael, Baldassare Peruzzi & Antonio da Sangallo the Younger each revised it afterward. Michelangelo took charge in 1547, discarded the accumulated complexity & returned to a Greek-cross plan with a single unified dome. He did not live to see it built. Giacomo della Porta carried the design through to completion in 1590 & the wider basilica was finished by 1626.
Details to Notice
The double-shell brick construction, an inner and outer dome built as separate structural layers, let Michelangelo use fewer ribs than earlier proposals while still keeping the whole thing standing. The ovoid profile pushes outward less forcefully than a true hemisphere would, reducing the buttressing needed at the base. Cracks that appeared in the eighteenth century were addressed by adding iron chains between the two shells, a reinforcement still doing its job today.

Heritage · Unesco Cultural · Sacristia A purpose-built sacristy raised behind St Peter's after two centuries of failed designs, now home to the Vatican Treasury.
What You're Looking At
The sacristy is a freestanding building on the south side of St Peter's Basilica, inside Vatican City, linked to the church by two covered passages. It contains sacristies for the Canons, the Beneficiaries and a Common Sacristy, plus the rooms of the Treasury of St Peter. The Common Sacristy is topped with an octagonal, lead-clad dome and holds an altar with a nineteenth-century mosaic copy of Caravaggio's Deposition.
The Story
A sacristy had stood here since the Constantinian basilica, known as the Antichissima, the oldest one. Plans for a replacement resurfaced under Pope Nicholas V in the fifteenth century but stalled at his death & Donato Bramante's demolition of the old basilica after 1506 left the church without a permanent sacristy for two and a half centuries; a temporary one was set up around 1575 in the former church of Santa Maria della Febbre. Carlo Maderno and Gian Lorenzo Bernini both drew up designs that were never built & a 1715 competition won by Filippo Juvarra also stalled for lack of money. Pius VI finally broke the deadlock in 1776, laying the foundation stone that September; Carlo Marchionni's building was finished in 1784.
Details to Notice
Founded in 1975, the Treasury of St Peter occupies part of the sacristy and displays papal tiaras, liturgical furnishings and Antonio del Pollaiolo's bronze tomb monument to Pope Sixtus IV. In the Common Sacristy, look up at the octagonal lead dome & note the mosaic reproduction of Caravaggio's Deposition over the altar, a nineteenth-century copy of the painting now in the Vatican Pinacoteca.

Film & TV · James Bond Spectre
The Rome car chase in Spectre (2015) races down the Lungotevere, the road that hugs the Tiber, with Vatican City and the floodlit dome of St Peter's standing on the night skyline across the water. Bond's Aston Martin DB10 and a pursuing Jaguar tear past Castel Sant'Angelo, the round papal fortress that guards the approach to the Vatican, before the chase ends with a car going into the river. The basilica itself stays a backdrop, the unmistakable shape that tells viewers in one frame that this is Rome.
Games · Assassins Creed The Vatican climax of Assassin's Creed II ends in a fistfight with the pope inside.
Assassin's Creed II (2009) builds to its finale inside the Vatican. The hero Ezio Auditore breaks into St Peter's Basilica to confront Rodrigo Borgia, the corrupt Pope Alexander VI, in a sequence that runs through a digital recreation of the basilica and the Sistine Chapel and culminates in a brawl at the altar. The 2010 sequel Brotherhood then turns the whole of Renaissance Rome into the game's open world, with St Peter's and Castel Sant'Angelo among the landmarks players climb. The studio modelled the buildings on the real architecture of the period.
