Pons Aelius: bridge of access to the mausoleum
When Hadrian decided to build his mausoleum on the right bank of the Tiber — where Castel Sant'Angelo stands today — he needed a direct connection to the Campus Martius and the heart of the city. Pons Aelius was completed in 134 AD and inaugurated together with the mausoleum in 139, a few months after the emperor's death.
The bridge was a formidable structure by the standards of its time: three central arches in travertine have survived almost intact and still carry the weight of pedestrians crossing the Tiber today. The slightly arched, hump-backed profile was as functional as it was scenic: it created a visual axis pointing towards the cylindrical mass of the mausoleum.
At the two ends stood four columns topped with gilded torches and celebratory sculptures of emperors from the Antonine dynasty. Nothing of these Roman decorative elements remains; what today transforms the bridge into an open-air museum is the Baroque renovation commissioned fourteen centuries later.
The Jubilee tragedy of 1450
On 19 December 1450, during the Jubilee proclaimed by Nicholas V, a crowd of pilgrims was crossing Pons Aelius on the way back from St Peter's. In the middle of the bridge one of the parapets gave way; panic spread instantly. In the crush that followed — made worse by the impossibility of turning back — approximately 172–200 people were trampled or fell into the Tiber.
The tragedy deeply shook public opinion and prompted the pope to demolish several houses at the bridge ends that had been obstructing pedestrian flow. Nicholas V then had two outer arches added on either side of the bridge — those that today flank the Roman arches — widening the carriageway.
But it was two centuries later that the bridge received its definitive appearance.
Bernini and the Angels of the Passion (1667–1671)
In 1667 Pope Clement IX entrusted Gian Lorenzo Bernini with the task of transforming the bridge parapets into a monumental procession. The project was theologically precise: ten angels, five on each side, each holding one of the instruments of the Passion of Christ — the physical symbols of suffering and redemption.
Bernini, nearly seventy at the time, personally designed all ten models. Execution was entrusted to his workshop:
| Angel | Instrument | Sculptor |
|---|---|---|
| Crown of Thorns | Woven crown | Bernini (original in Sant'Andrea delle Fratte) |
| Titulus Crucis (INRI) | Scroll with inscription | Bernini (original in Sant'Andrea delle Fratte) |
| Column | Column of the flagellation | Ercole Ferrata |
| Scourge | Cords and rods | Lazzaro Morelli |
| Garment and Dice | Cloak/lot casting | Paolo Naldini |
| Sudarium of Veronica | Veil with imprint | Cosimo Fancelli |
| Cross | Latin cross | Girolamo Lucenti |
| Nails | Three nails | Girolamo Lucenti |
| Sponge and Reed | Reed with soaked sponge | Antonio Raggi |
| Lance | Lance that pierced the side | Domenico Guidi |
Bernini's two originals
Bernini personally sculpted two of the angels: the one holding the Crown of Thorns and the one with the Titulus Crucis (the scroll bearing the INRI inscription). When Clement IX saw them finished he was so struck by their quality that he decided not to expose them to the weather: he had them brought to his private palace as works of art to be contemplated, not architectural elements.
After the pope's death (1669), the two sculptures were donated to the basilica of Sant'Andrea delle Fratte, a short distance from Piazza di Spagna, where they remain today. Copies made by the workshop were placed on the bridge.
The originals kept in Sant'Andrea delle Fratte are considered among the most powerful works of the late Bernini: the swirling movement of the drapery, the body twisting on itself, the sorrowful face turned upwards — everything expresses an emotional tension that the copies on the bridge cannot quite equal.
The bridge as iconographic journey
Crossing Ponte Sant'Angelo is not simply passing from one bank to the other: it is walking a horizontal Via Crucis. Approaching the castle from Piazza Pia, one crosses an ideal threshold of meditation. The angels, with their instruments of the Passion, guide the visitor towards the castle that for centuries was simultaneously fortress, prison, and papal palace.
Bernini exploited the nature of the bridge — narrow, crossed in single file — to create an effect of procession, with the sculptures alternating on either side like officiants at a silent ceremony. The result is one of the first examples of Baroque urban space in motion: a visual and spiritual experience that still precedes entry into the museum today.
Practical visit
The bridge is pedestrian only (closed to vehicular traffic since 1887). There are no opening hours or tickets: it is always accessible.
The best time to photograph the angels is early morning or late afternoon, when raking light brings out the sculptural volumes and casts deep shadows across the drapery. At sunset, the orange reflection on the Tiber and the dark silhouette of the castle in the background compose one of Rome's most recognisable views.
