Built on the site of the 1st century AD Stadium of Domitian, this city square is the venue that was once used by ancient Romans for festivals and sporting events. Today Piazza Navona is a pedestrian’s paradise where restaurants line the perimeter and the magnificent Fountain of the Four Rivers structure grace this elongated oval. One cannot miss the church of Sant’Agnese in Agone, a 17th century baroque church that commands such fine craftsmanship, such splendour and such dedication to faith that is almost impossible to find in today’s modern world. For those who would like to bring home paintings as souvenirs, there are plenty of artists’ works on sale here.
