With your admission ticket, you will visit the underground levels of Piazza Navona, first opened to the public in 2014. Many people know Rome's Piazza Navona, but few know about its underground treasures. Descend below the famous square to visit the Stadium of Domitian, a Roman archaeological dig, only open to the public since 2014. Now on the UNESCO World Heritage list, the underground site contains the ruins of a masonry stadium, which is thought to be the only one built in ancient Rome. Explore at your own pace and make use of an audio guide to understand the stadium's history.
