Piazza Navona

The square sits exactly on the track of the stadium Domitian built around AD 86 for athletic contests, which is why it is so long and narrow. Under the north end you can still see its remains in a small underground museum.

It has three fountains. The central one, Bernini's Four Rivers, shows the Nile, the Danube, the Ganges and the Río de la Plata around an Egyptian obelisk. Opposite stands Sant'Agnese in Agone by Borromini, his great rival: legend says the statues shield their eyes from his church, though the fountain was finished first.
