Piazza Navona is a great place dating back to the 15th century. Before that time, the place called the Circus Agonalis, a stadium built 86 years before Christ. Sports venues and other events took place at this place. When the space was rebuilt, it was surrounded by ruins on which were houses built to form the framework of the current Piazza Navona. However, there are still remains of the old Circus Agonalis.
Today Piazza Navona is the place for artists who paint watercolors and oil paintings from all areas of Rome. There are many attractions at Piazza Navona for example
The Basilica of Sant Agnese in Agone, which was built in 1652
Fontana Quattro Fiumi
Fontana del Nettuno
Palazzo Braschi (here is the Museo di Roma with a large collection of paintings, drawings, photographs, books, ceramics and furniture that tell Roman history from the Middle Ages to the 20th century)
