It is larger than it looks
The greatest illusion of St Peter's is its scale. Inside, nothing seems extraordinarily large — yet everything is. The letters of the inscription beneath the dome are 2 metres tall. The baldachin is 28.5 metres high — as tall as a nine-storey building. The entire basilica is 211 metres long. Perception is distorted because everything is consistently proportioned: there is no single out-of-scale element to serve as a reference.
Only when you approach a human figure at the base of one of the piers do you begin to understand where you truly are.
The Pietà is larger than life
Michelangelo made the Pietà in larger than life-size dimensions: the Virgin, if standing, would be over 190 cm tall. The choice was not accidental. A life-size figure with the adult Christ across her lap would have appeared crushed. By increasing the proportions of the Madonna and widening her mantle, Michelangelo turned a compositional problem into an expressive choice.
The worn foot: devotion and erosion
The right foot of the bronze statue of St Peter — traditionally attributed to Arnolfo di Cambio, 13th century — has been worn away by millennia of kisses and touches from the faithful. An estimated 5–6 million visitors pass through each year. On average, the foot has been brushed by tens of thousands of hands every day for centuries. There is no restoration: the wearing is part of the statue's own history.
Bronze stolen from the Pantheon?
For the baldachin, Bernini used approximately 100,000 kg of bronze, much of it sourced from the porch of the Pantheon, where it had clad the structural beams. Pope Urban VIII (Maffeo Barberini) authorised the stripping. The contemporary satirist Pasquino — Rome's "talking statue" — commented with the famous line: «Quod non fecerunt barbari, fecerunt Barberini» — "What the barbarians did not do, the Barberini did." Urban VIII belonged to the Barberini family.
The Passetto di Borgo: a papal escape route
During the Sack of Rome in 1527, the Landsknecht troops of Charles V pillaged the city for weeks. Pope Clement VII escaped via the Passetto di Borgo, the covered elevated corridor linking the Vatican to Castel Sant'Angelo. He took refuge in the fortress for approximately seven months. The corridor, roughly 800 metres long, is still partly open to visitors.
The "Cathedra" and the wooden chair
The monumental bronze throne by Bernini in the Cathedra Petri — 7.5 metres high, surmounted by the Holy Spirit window — conceals inside it an oak wooden chair dating from the 9th century. It was long believed to be the bishop of Rome's throne from apostolic times. Recent historical analysis suggests it is more likely a Carolingian chair, a gift from Charles the Bald to Pope John VIII in 875 AD. The apostolic wood has become the baroque throne: the real story is almost as extraordinary as the legendary one.
The signature of the Pietà: the story of an anger
According to Giorgio Vasari, Michelangelo signed the Pietà — the only work he ever signed — after overhearing a group of Lombard visitors attributing it to Cristoforo Solari. Furious, he returned by night and carved the words on the sash running across the Virgin's breast: MICHAEL ANGELUS BONAROTUS FLORENTINUS FACIEBAT. The Latin verb faciebat — "was making" — is in the imperfect tense, as if to suggest the work was still in the process of becoming perfect.
The Holy Door: open only during the Jubilee
The Holy Door — the last of the five doors of the basilica, on the right side — remains bricked up for years at a time. It is opened by the Pope only at the beginning of a Holy Year (every 25 years, or in extraordinary jubilees). The opening involves a ritual gesture: the Pope strikes it three times with a golden hammer before the masons remove the wall. In the Jubilee year, those who pass through the door and fulfil certain spiritual conditions receive a plenary indulgence.
The dome Michelangelo would not have recognised
Michelangelo designed the drum and dome imagining the visitor would see it from above the apses — walking around it. He had planned a shorter nave. When Carlo Maderno extended the nave in 1607–1614, the façade ended up blocking the dome's drum from view along Via della Conciliazione. Today the dome can be seen in its entirety only from a certain distance or from the sides. Michelangelo, by his own words, would not have approved of Maderno's solution.

Frequently Asked Questions
Is it true that the bronze of the baldachin came from the Pantheon? Partly yes. A significant portion of the bronze came from the structure of the Pantheon's porch by order of Urban VIII in 1626. The source is Bernini himself. The Pantheon lost some of its bronze cladding, but the main concrete structure (opus caementicium) remained intact.
Why is the signature on the Pietà in the imperfect tense ("faciebat")? It was traditionally interpreted as a statement of artistic humility: the imperfect tense implies an ongoing process, a perfection never definitively achieved. Some historians see it as a reference to the classical Greek tradition, where sculptors used similar constructions.
