One of the most beautiful baroque squares in the world. In antiquity, this place served as an athletic stadium and also as a theater. The capacity of this cultural and sports venue exceeded 20,000 visitors. During the Middle Ages, markets were moved here. In the middle of the 17th century, the square used to be flooded by water during summer weekends so that rich people and the nobility of Rome could enjoy boating in the city center. The Pamphili family was one of the richest families in Italy. They built their palace on the square and now is used as the Brazilian Embassy. The family also financed two of the most outstanding buildings on this square, namely the Church of St. Agnes and the famous Four Rivers Fountain. Today, Piazza Navona is full of bars, restaurants, painters, and musicians.
