A 5th-century basilica built to hold the chains of St Peter, and Michelangelo's most theatrical sculpture.
Last updated August 23, 2026
In a nutshell: one church, two treasures: the chains said to have bound St Peter, and Michelangelo's colossal Moses - the centrepiece of an unfinished papal tomb. The basilica is free, quiet and five minutes from the Colosseum up the hill. Pair it with the Monti quarter or the Esquilino's basilica, and start from the district overview.
A 5th-century basilica built to house the shackles said to have bound St Peter when he was imprisoned in the Carcere Mamertino - 'in Vincoli' means 'in chains'. The chains arrived in two pieces and, according to legend, miraculously joined together when they were reunited. The church's theatrical centrepiece is Michelangelo's colossal Moses sculpture (1505), the centrepiece of his unfinished tomb for Pope Julius II: Michelangelo originally envisaged 40 statues but was sidetracked by the Sistine Chapel, and Julius ended up buried in St Peter's Basilica instead.

The horns came from a mistranslation of a biblical passage describing rays of light issuing from Moses' face, rendered as 'horns'; Michelangelo was aware of the mistake and, devilishly, gave Moses horns anyway. Flanking him are statues of Leah and Rachel, probably completed by his students, while a statue of Julius II lolls somewhat saucily in the centre above.
Begin at the right-hand end of the church, where a wall of marble figures clusters around Moses. The basilica itself dates from 440, when it was raised to shelter Peter's chains, ranking among the city's most ancient places of worship. A thorough remodelling in 1475 changed the look of the building but not its ancient floor plan, and the 20 Doric columns that line the wide nave survive from the original structure.
On the altar, a reliquary of gold and glass displays what tradition identifies as the very chains that held Peter. In fact there are two sets, joined together. One set supposedly bound Peter during the imprisonment he shared with Paul at the Mamertine Prison, Rome's grim lock-up beside the Forum. The second set comes from the story in Acts 12, when Herod had Peter locked up in Jerusalem: an angel woke the sleeping apostle, the chains fell from his hands, and he was led out to safety. Raphael painted the escape scene; his canvas is now kept with the Vatican Museums, while a 1577 painting by Jacopo Coppi sits on the left-hand wall behind the altar. Late in the ancient era the Jerusalem set made its way to Rome, arriving as a present from the empress of the East - a moment Coppi painted once more, this time on the apse's right-hand wall - and tradition holds that the two sets fused together the instant they met, joined by a miracle.
Everything else in the basilica rewards a slow look. The central ceiling canvas, painted around 1700, shows the relics at work: a man tormented by demons is healed before the Vatican basilica. The marble coffers painted around it seem deeply carved yet are perfectly flat. Along the side aisles, funerary monuments carved with skulls and scythe-bearing death figures preach the 17th-century fashion for memento mori - remember that you must die.
Michelangelo's Moses sits at the centre of that marble wall, caught in a moment of barely contained fury. He has just come down from meeting God face to face; sensing trouble back home, he turns slowly towards the Israelites dancing around the golden calf, his anger mounting as he glares. His muscular left leg is tucked under him and tensed, as if he is about to leap from the chair and bring the Ten Commandments - held beneath his arm - down on the guilty. The cascading beard ranks among the great achievements of art history. Were he to stand, Moses would top out at about 13 feet, nearly as tall as Michelangelo's own David, and his bare, powerful arms radiate strength. The statue was finished around 1515, once his four-year stint frescoing the Sistine ceiling's seated prophets was done.
Like so much of Michelangelo, Moses is simultaneously at rest and in motion: he sits, yet the leg is tensed, the head turns, the fingers fidget. Some read this restlessness as the sculptor's Neo-Platonic conviction that the soul, trapped inside the body, longs to escape its cramped prison; others see the figure itself straining to break free of the surrounding stone. A fanciful story has it that Michelangelo, exasperated by his struggle to call the figure out of the marble, struck it with his hammer - the dent is still there, on the right knee - and ordered it to speak.
Then there are the horns, the statue's most famous quirk. A medieval mistranslation turned the Hebrew phrase for the radiance around Moses' face into 'horns'. Michelangelo knew perfectly well what the original meant, yet he kept the horns anyway, to lend the prophet an aura of terribilità - the intimidating, smouldering charisma he shared with Julius II and with Michelangelo himself. The result radiates a simmering, barely controlled menace.
Moses anchors the lowest tier of a two-storey wall of marble crowded with figures - a shrunken, patchwork echo of the stupendous tomb it was meant to crown. In 1505 the freshly crowned Julius II hired Michelangelo, still a young man, to build a monumental tomb for St Peter's Basilica. The excited sculptor sketched a three-storey wedding cake of marble set with 48 sculptures and bronze reliefs, capped by an outsized effigy of the vain pontiff, with Moses meant for a corner of an upper level, his gaze turned from the monument. He then travelled to the Carrara quarries, picked out 100 tons of marble and began work.
Then the pope switched course and had Michelangelo fresco the Sistine ceiling instead. The ceiling fresco kept him busy for only four years; he then rushed back to the project, only to watch the funding evaporate when Julius died in 1513. Michelangelo kept coming back to the project, in bursts and pauses, for four decades before moving on for good, and Julius was put to rest in an unadorned tomb in the Vatican basilica. In 1542 the leftover fragments were brought to San Pietro in Vincoli, where Michelangelo's assistants assembled what they could. What survives today falls far short of that vision: the monument was meant to stand fully in the round and to be five times as large. The finest figures had gone elsewhere: the Slaves, for instance, now reside at Florence's Accademia, and the Louvre holds the pair. Michelangelo's helpers worked from his original written instructions, yet most of the pieces were gone.
Of all the figures in the scheme, only Moses and the Slaves now in the Louvre were finished by Michelangelo's own hand. The two women at Moses' sides are Jacob's sister-wives: Leah on our right, Rachel on our left. Michelangelo started them, and his students most likely saw them through. On the storey above, a sculpture of the Virgin with the Christ Child hovers over a recumbent, pensive Julius II on his bier. The surviving decoration - nearly 50 statues bound together with Pompeii-style garlands and curving proto-Baroque scrolls - hints at the ambition of the monument as first conceived. Giorgio Vasari claimed the finished monument was meant to outdo any tomb, imperial or ancient, ever raised. Michelangelo died certain the tomb had devoured his most productive decades, and today the whole design lives only in the imagination.
Admission is free, and the church welcomes visitors daily from 7:15 to 12:30 and again from 15:00 to 19:00; from October through March the afternoon closing comes an hour earlier, at 18:00. Visitors must dress respectfully: shoulders have to be covered, and shorts or skirts cut above the knee are not allowed. Count on about 30 minutes inside, and call +39 06 9784 4950if you need current information.
Getting there: the basilica perches on the hill above the Colosseum, ten minutes on foot to the north. Leave Colosseo Metro station and ride the escalator that begins just within the station's exit (look for the brown sign naming S. Pietro in Vincoli), cross over the pedestrian bridge, then climb Via della Polveriera to the top; a left turn lands you at the church. A stairway about 50 yards further east offers a second route up. For a shorter but steeper route, use Cavour Metro station: half a block downhill along Via Cavour, then up the long pedestrian stairway of Via di San Francesco di Paola, arriving right at the church.
