Piazza Navona — Stadio Domiziano e Fontane del Barocco, Roma

The finest Baroque piazza in Europe — an elongated oval that preserves exactly the footprint and dimensions of the stadium built by the Emperor Domitian in 86 CE, surrounded by the palaces and facades that the Pamphilj family (patrons of Borromini and Bernini) built in the seventeenth century, with at its centre the most theatrical fountain composition in the world: Bernini’s Fontana dei Quattro Fiumi (1651), four river gods supporting an Egyptian obelisk on a hollow rock from which water falls in multiple directions.

At a glance

Piazza Navona occupies the site of the Circus Agonalis — the stadium built by the Emperor Domitian in 86 CE for athletic games (agones) in the Greek tradition. The stadium measured 276 by 106 metres and held approximately 30,000 spectators; its curved north end gave the piazza its distinctive oval form. After the fall of Rome, the stadium’s seating was built over by medieval houses; the arena floor became a public space. By the fifteenth century it was the most important market square in Rome (the Wednesday market remained here until 1869).

The Baroque transformation of the piazza was driven by the Pamphilj family, whose palace (Palazzo Pamphilj) occupies the entire western side of the square. Pope Innocent X (Giovanni Battista Pamphilj, pope 1644–1655) commissioned Bernini to create a central fountain (1651) and Borromini to redesign the church of Sant’Agnese in Agone (begun 1653) on the western side. The resulting ensemble — Bernini’s fountain, Borromini’s concave church facade, and the three Baroque palaces framing the oval — is one of the defining achievements of seventeenth-century European architecture.

History

The Stadium of Domitian was built in 86 CE as part of Domitian’s programme of Hellenising Roman culture — introducing Greek athletic games (Agones Capitolini) to Rome alongside the traditional gladiatorial games of the arena. The stadium was the largest in Rome (larger than the Circus Maximus in its proportions, though smaller in absolute size); its curved form, derived from the Greek stadium tradition, was unusual in the Roman urban fabric. After the conversion of the arena floor to residential use in the medieval period, the memory of the ancient building was preserved in the name: “in agone” → “navone” → “navona.”

The seventeenth-century transformation of Piazza Navona represents the high point of Papal Baroque urbanism. Innocent X, who had grown up in the Pamphilj palace on the western side of the piazza, determined to make the square a monument to his family and his papacy. The commission of the central fountain to Bernini was politically complicated: Bernini had been the favourite architect of Urban VIII (Innocent’s predecessor and political enemy); Innocent initially refused to use him, then was persuaded by a small wax model of the fountain that Bernini made and had placed where Innocent would encounter it. The fountain was completed in 1651, two years before Innocent’s death.

What you see

The piazza is best understood from the north end — the curved terminus that preserves the hemicycle of Domitian’s stadium most clearly. Standing at the north end and looking south, the full 276-metre length of the oval is visible: the Fontana del Moro (south end, 1575, with additions by Bernini) and the Fontana di Nettuno (north end, 19th century) flank the central Fontana dei Quattro Fiumi. The western side is dominated by Borromini’s concave church facade — a deliberate response to the Baroque principle that a building’s exterior should engage its surroundings rather than merely face them; the concave form pulls the eye toward the central obelisk, with which it is in dialogue across the 100-metre width of the piazza.

The Fontana dei Quattro Fiumi (1651): four colossal river gods — each representing one of the four great rivers of the known world (Nile with covered head, because its source was unknown; Ganges; Danube; Río de la Plata with coins, symbol of the New World’s riches) — are arranged on a hollowed travertine rock from which water falls in complex patterns. An Egyptian obelisk (originally from the Circus of Maxentius, 4th century CE; surmounted by the Pamphilj dove) rises 16 metres from the centre of the rock. The arrangement was innovative in placing the obelisk on a hollow structure through which the rock, the water, and the figures can be seen simultaneously.
