Underground Rome and Domitian Stadium Tour

Piazza Navona owes its shape to the ancient Domitian Stadium.

This massive structure, which could hold around 30,000 spectators, featured a 240-meter-long and 65-meter-wide track where athletic competitions were held. Piazza Navona occupies the arena space, and all the surrounding buildings are built on the remains of the stadium’s stands.

The Domitian Stadium was the first permanent sports venue in Rome made of masonry. It was commissioned by Domitian, the third emperor of the Flavian dynasty, in 86 AD. The stadium remained in use until the 5th century.

Visitors can access an underground area where they can observe structures of the stadium, including archways supported by pilasters and radial brick walls placed in an arc. Steps leading to the upper seating rows are still visible, and some walls retain stucco coatings.

As you stroll through Piazza Navona, you will uncover not only the Baroque beauty of the square but also the ancient remains of the Domitian Stadium, silent witnesses to the grandeur of Imperial Rome.
