Originally, the square was supposed to be used for the city's athletic competitions. This is the reason for its elliptical shape. It was built on the ruins of the stadium of Domitianus from the first century. During ancient times it was used for horse races and is the only remnant of the nostalgic race track of the Romans.
Around the square there are beautiful Baroque palaces from the 17th century, the most famous of which is the church of Sant'Agnese in Agone.
Please note that the square is inviting and beautiful, but the prices of shops and restaurants are certainly high. Try to walk a little farther from the square and see how the prices gradually decrease.
Entrance to the square with vehicles is not permitted, unless you are traveling on a licensed vehicle. However, public transport will help you reach it and also travel to many places in the area, such as the Colosseum, the Forum and more.
Take special notice of the tall obelisk, which came from Egypt at the command of one of the Popes, to symbolize the triumph of Christianity over the Muslim world. The symbol of the pigeon you see, was commissioned by the Pamphili family from Bernini.
On weekends and in the evening you can see many artists and painters in Piazza Navona. The early morning is the ideal time to enjoy the piazza, as it is less crowded than during the day.
