One of the most remarkable squares and best places to visit in Rome is Piazza Navona. The famous square therefore owes its elongated shape to its original purpose as a Roman athletics stadium. Interesting sights on the square include a number of fountains, such as the ‘La Fontana dei Quattro Fiumi’ by Bernini, an interesting obelisk, and you can visit the excavations of the old stadium of Domitianus. In addition, Piazza Navona is a lively square with many street performers, cafés and terraces.
