Stadium of Domitian (Stadio di Domiziano)

The basics

Known as the Circus Agonalis in Roman times, the Stadium of Domitian was built by Emperor Titus Flavius Domitianus to hold athletic events, and is believed to have been the only stadium built in masonry in ancient Rome. Fragments of the original stadium can still be seen above ground, but much of the ruins are beneath Piazza Navona. Join an underground Rome tour to visit the section of the archaeological site opened to the public in 2014, which features multimedia exhibits to illustrate the history of the sport, as well as the history of the stadium itself. The Stadium of Domitian is an example of the many layers of history that exist beneath modern Rome, and underground tours usually touch on hidden Roman ruins along with early Christian churches and medieval crypts. To get an idea of the size of the ancient stadium, opt for a tour of Rome’s main squares and fountains that includes a turn through Piazza Navona, built in its exact size and shape.
