This is one of the most characteristics places which recalls the eternal spirit of Rome. The elliptical shape of this square is due to Emperor Domitian: in AD 86 he had a stadium built on this site in which he instituted games in the Greek style. Domitian stadium was stripped of its marbles in 356 by Constantinus II on a visit to Rome and by the 5C it was in ruins. It came to life again during the Renaissance when it was rebuilt by Pope Innocent X in 1644, turning the square into one of the most beautiful sights in Rome. There are three fountains in the square: the one of the Rivers (created by Bernini), the one of the Moor and the fountain of Neptune.
