Piazza Navona Piazza Navona Piazza Navona () is a square in Rome, Italy. It is built on the site of the Stadium of Domitian, built in the 1st century AD, and follows the form of the open space of the stadium. The ancient Romans went there to watch the "agones" ("games"), and hence it was known as ""Circus Agonalis"" ("competition arena"). It is believed that over time the name changed to "in avone" to "navone" and eventually to "navona". Defined as a public space in the last years of 15th century, when the city market was transferred there from the Campidoglio, Piazza
