The Stadium of Domitian is an ancient Roman stadium whose remains lie beneath and around Piazza Navona. Built for athletic competitions, it gave the famous square its long, distinctive outline—and a fascinating secret to discover below street level.

Piazza Navona is one of the most memorable places to wander in Rome. But once you know what stood here nearly two thousand years ago, the square becomes more than a beautiful backdrop: its shape starts to tell a story.

What was the Stadium of Domitian?

Emperor Domitian commissioned the stadium in the first century AD for athletic contests. Its elongated arena accommodated events inspired by Greek athletics. Over the centuries, buildings developed over and around the ancient structure, while the open area preserved the shape that would become Piazza Navona.

According to Rome’s official tourism office, archaeological remains can be seen below today’s street level. The excavated area offers a way to connect the life of an ancient city with the streets above it.

What can you see underground?

Visitors can explore a preserved archaeological area and look at surviving masonry and architectural elements from the stadium. Exhibitions and visitor routes can change, so consult the official visitor information linked by Turismo Roma before making plans.

Look back at the square afterward: its long form becomes easier to understand when you imagine spectators gathered around an arena rather than café tables and fountains.

How to plan your visit

  • Location: The archaeological area is at the northern end of the Piazza Navona area. Confirm the visitor entrance before leaving.
  • Tickets and hours: Check current opening times, admissions and any closures with the site’s official visitor information.
