St Peter’s Basilica is the largest church in Christianity and the spiritual centrepiece of the Roman Catholic world. Rising above Vatican City with Michelangelo’s vast dome on the skyline of Rome, it stands over the place traditionally held to be the tomb of Saint Peter, the apostle whom Catholics regard as the first pope. For pilgrims and visitors alike, it is one of the most overwhelming buildings ever raised.
Built Over the Tomb of an Apostle
Tradition holds that Saint Peter was martyred in Rome in the first century and buried on the Vatican hill. In the 4th century the emperor Constantine built a great basilica over the site. By the Renaissance that ancient church was crumbling, and in 1506 Pope Julius II began an audacious project to replace it entirely. The new basilica took 120 years to complete, finished in 1626, and drew on the genius of a succession of the age’s greatest architects.

Michelangelo’s Dome and Bernini’s Baldachin
Several masters shaped the building – Bramante, Raphael, and above all Michelangelo, who became chief architect in 1547 at over seventy years of age and designed the soaring dome that crowns it. Visitors can climb to the top of that dome for one of the finest views in Rome. Inside, beneath the dome and over the high altar, stands Bernini’s towering bronze baldachin, a swirling canopy of dark, gilded columns marking the spot above the apostle’s tomb.
The Pietà and the Scale of the Interior
Near the entrance, behind glass, is Michelangelo’s Pietà – the tender marble sculpture of Mary holding the body of Christ, carved when the artist was in his twenties. Beyond it the nave stretches away on a scale that is hard to grasp; markers in the floor show how the world’s other great churches would fit inside. Mosaics, marble, gilded stucco and monumental statues fill every surface, a deliberate statement of the power and grandeur of the Church at the height of the Baroque.
Visiting the Basilica
Entry to the basilica itself is free, though there is usually a long security queue across St Peter’s Square, and a modest charge to climb the dome or visit the treasury and the Vatican Grottoes below, where many popes are buried. Modest dress is required – shoulders and knees covered – and the calmest time to visit is early morning, soon after the doors open.
