Rome's most theatrical square sits on the floor of an ancient racetrack. Three fountains run down its spine, street painters work between the cafe tables, and Bernini's Fountain of the Four Rivers holds the center with an obelisk balanced over a hollow grotto. No other square in the city gathers this much baroque theater into one open room.
The piazza keeps the exact footprint of the Stadium of Domitian, opened around 86 AD, and the buildings around you stand on its seating. Even the name descends from the Greek athletic games once held here, the agones, worn down over the centuries into Navona. Innocent X rebuilt the square as the Pamphili family showpiece in the 1650s, and for two centuries Rome plugged the fountain drains on hot August weekends and flooded the center for mock naval displays, a tradition that lasted into the 1860s.
The famous story that the Rio de la Plata throws up his arm to shield his eyes from Borromini's church facade cannot be true. The fountain was finished in 1651, two years before Borromini took over Sant'Agnese in Agone. Just north of the square at Tor Sanguigna you can step below street level and stand inside the excavated arches of the original stadium.
