Introduction
Navona Square is one of Rome’s most popular squares. Tourists love it for its fountains, open-air cafés, and Baroque palaces. But what many people don’t realize is that the square sits on top of an ancient Roman stadium: the Stadium of Domitian.
About 4.5 meters below today’s ground level, you can have one of the Rome Underground Tours. Visiting it gives a clear, simple way to understand how the Rome of today was built over the Rome of the past.
Navona Square History: From Roman Stadium to Baroque Square
Navona Square is famous for its fountains, especially Bernini’s Fountain of the Four Rivers, and the church of Sant’Agnese, designed by Borromini. It is a Baroque masterpiece and a favorite spot for photos.
The shape of the square is unusual. Long and narrow, with rounded ends, it copies the footprint of the Stadium of Domitian that once stood here. Built in the 1st century AD, the stadium determined the layout of the square. So when you walk through Navona Square today, you are following the same lines that once framed a Roman sports arena.
The Stadium of Domitian: Rome’s Ancient Sports Arena
Emperor Domitian had the stadium built in 86 AD for athletic contests called the Certamen Capitolino Iovi, games held in honor of Jupiter. These were not gladiator fights but athletic competitions modeled on the Greek style.
The stadium was the first permanent stone stadium in Rome. It was 275 meters long and 106 meters wide, with room for about 30,000 spectators. Its rectangular plan, with one curved end, is very similar to a modern track-and-field stadium. The structure used brick and concrete, finished with travertine and stucco.
Although smaller than the Colosseum, the stadium was important because it promoted athletics instead of violent spectacles. Romans, however, often preferred gladiators and beast hunts, so these athletic games never reached the same popularity.
Sports and Culture in Ancient Rome
The events included running races, wrestling, boxing, the pentathlon (five different athletic contests), and the pankration, a mix of boxing and wrestling with very few rules. Romans considered athletics less exciting than gladiatorial fights, but the competitions still attracted crowds.
Many athletes were professionals from Greece or the eastern provinces. Roman citizens could also take part, and winners received honors, money, and sometimes even Roman citizenship. Unlike gladiators, athletes could improve their social status, which made these games different from other Roman spectacles.
Underground Tour: Visiting the Stadium Today
Over the centuries, the stadium was covered by new buildings and eventually by Piazza Navona itself. Excavations have made part of it visible again. Today, visitors can tour underground and go into a small archaeological museum.
Walking through the site, you see walls, arches, and passages that once supported the seating areas. Even though only part of the stadium is exposed, it is easy to imagine the scale of the original structure.
The museum shows models and reconstructions that explain how the stadium looked in Domitian’s time. Displays also provide information on the games, the athletes, and the history of the building. The visit is straightforward and helps connect what you see above ground with what lies beneath.
A Journey Through Time: From Ancient Arena to Modern Square
The experience of visiting the stadium is simple but impressive. Above ground, Piazza Navona is busy with fountains, restaurants, and people enjoying the atmosphere. Below ground, you find the quiet remains of a Roman stadium.
Seeing both levels together shows how the city has changed: from the Roman Empire to the Baroque age to the Rome of today. It is a clear example of how history in Rome is built layer by layer.
Navona Underground Tour: Why the Stadium of Domitian is Worth Seeing
The Colosseum and Roman Forum are famous and often crowded. The Stadium of Domitian is less well-known, which makes it easier to visit without long lines.
It is not as large as other Roman ruins, but it is unique because it explains directly why Piazza Navona looks the way it does. Understanding that connection makes the square more meaningful. Once you see the underground remains, the shape of the piazza above makes perfect sense.
Conclusion
Piazza Navona is beautiful for its fountains and Baroque buildings, but it also hides part of Rome’s ancient past. The Stadium of Domitian, preserved underground, shows how the city has always changed but never lost its history.
Visiting the site is a clear and simple way to see two Romes at once: the lively square above and the ancient arena below. It is an accessible hidden gem that helps anyone, even without deep historical knowledge, understand how extraordinary the city really is.
