CIRCO AGONALE,

one of the finest squares in Rome, sometimes called Piazza Navona. It takes its name from being the site of the Circus Agonalis. Fêtes are held here during Carnival, and a fair at the Epiphany.

Notice the three fountains—the centre one by Bernini: four figures, representing four rivers, recline on a craggy rock; on its top stands an Egyptian obelisk, at its base a lion and a sea-horse.
