With its unique atmosphere and baroque design, Piazza Navona is often described by visitors as the most beautiful square in the world. It owes its present appearance to Pope Innocent X, who wanted to express the power and wealth of his family, the Pamphilj, with it.
It was built on the site of the Domitian Stadium and retains its original layout. The stadium was built in 86 B.C. for athletic games in the Greek style and could hold more than 30,000 spectators. Remains of the stadium can be seen below the church of Sant’Agnese and to the north of the square.
To the north is the Fontana di Nettuno, to the south the Fontana del Moro and in the middle the Fontana dei Quattro Fiumi. In front of the Fontana dei Quattro Fiumi there is the church of Sant’Agnese in Agone.
