Piazza Navona follows the outline of a Roman stadium

Piazza Navona is a long Roman square whose shape preserves the track of an ancient stadium. Domitian’s stadium occupied the site in the first century AD, while Bernini’s Fountain of the Four Rivers and Sant’Agnese in Agone give the space its Baroque character.
The stadium beneath the long piazza
The ground plan remains Piazza Navona’s clearest historical feature. The square follows the elongated perimeter of the Stadium of Domitian, a venue completed in 86 AD for athletic contests and horse races.
The ancient arena was known as the Circus Agonalis, a name connected with agonal games. The modern name developed through medieval forms connected with “in agone”. Beneath the surrounding buildings, archaeological remains preserve parts of the stadium’s original construction.
The track survives as open urban space, while buildings occupy the zones once associated with the stadium’s seating. This relationship gives Piazza Navona a readable connection between Roman entertainment architecture and the later city.
Bernini’s rivers at the centre
The Fountain of the Four Rivers occupies the centre of Piazza Navona. Gian Lorenzo Bernini completed it in 1651 for Pope Innocent X Pamphilj, whose family palace faces the square.
Four monumental river figures represent the Danube, the Ganges, the Nile and the Río de la Plata. An obelisk rises above the sculptural group, which combines rock, water, architecture and human forms in one composition.
The fountain belongs to the major Baroque transformation of Piazza Navona. Its central position creates a strong visual axis through the long open space, while the surrounding façades supply a continuous architectural frame.
The fountain’s four rivers express a geographical vision of the world known in seventeenth-century Europe. Its four river figures are paired with an obelisk and a rocky base.
Sant’Agnese and the Pamphilj buildings
On the western side, Sant’Agnese in Agone faces the square with its concave Baroque façade and prominent dome. Francesco Borromini worked on the church during the seventeenth century, and the building forms part of the Pamphilj architectural ensemble.
The church is associated with Saint Agnes, whose name is preserved in the dedication. Its interior contains a centralised plan, decorated surfaces and a dome that continues the vertical emphasis of the exterior.
Palazzo Pamphilj occupies a substantial part of the western side. The palace, the church and Bernini’s fountain belong to the same broad period of papal building in Rome, although their architectural languages differ.
The square also contains the Fountain of Neptune and the Moor Fountain. Together with the central fountain, they place water sculpture at several points along the ancient stadium’s open track.
Piazza Navona became a public urban space in the late fifteenth century, when Rome’s market moved there from the Campidoglio. Its later Baroque appearance developed under Innocent X, who reigned from 1644 to 1655. The square’s stadium-shaped perimeter remains visible between the palaces and fountains.
