The contours of the most beautiful Baroque piazza of Rome resemble the outline of an ancient stadium (the Circus of Domitian) where athletes competed. The remains of the stadium can be seen in the vaults under the church Sant'Agnese in Agone where the virgin Agnes refused to marry a pagan and was undressed to be executed. At once, her body miraculously had been covered by her long hair that had grown on the spot. The square acquired its modern look in 7th century when Pope Innocent X whose familial palace was located there, commissioned a new church, a palace and a fountain. The fountain is called the Fountain of the Four Rivers (Fontana dei Quattro Fiumi ) as it symbolizes four rivers of four continents (the Nile, the RГo de la Plata, the Ganges, the Danube). The whole architectural ensemble was created by Bernini. There is no other square in Rome that would compare to piazza Navona.
