Introduction
Piazza Navona is a public square in Rome built on the site of the 1st-century Stadium of Domitian, whose elongated shape it still follows. It is one of the city's most famous Baroque squares, known for its three fountains—including the Fontana dei Quattro Fiumi—and the Church of Sant'Agnese in Agone, drawing crowds year-round with cafes, street performers, and lively atmosphere.
