The Piazza Navona, or "Circo Agonale", occupies the spot where once stood the stadium of Domitian, which held up to 30.000 spectators. Here are three magnificient fountains. The one in the centre is the Fountain of the Four Rivers by Bernini. The church of S. Agnese in Agone, is built on the spot where, according to tradition, the virgin Agnese, denuded before her martyrdom, was mantled in her hair, which had grown miraculously to cover her. It is a magnificent Baroque building designed by G. Rainaldi and Borromini. Beneath it are some remains of the original church and of the Circus of Domitian.
