Inside the Passage of Commodus — The Colosseum’s newly opened secret tunnel

Walk through the dimly lit underground corridor once reserved for emperors. Newly restored brick walls, vaulted ceilings, and moisture-sealed floors reveal the engineering precision of ancient Rome. Guides explain how Commodus used this route to enter the arena unseen.

At the junction beneath the Colosseum, see where the tunnel meets the arena’s hypogeum, a maze of lifts and trapdoors once used for gladiators and animals. The lighting recreates the eerie atmosphere of the Colosseum’s backstage before battle.

Glimpse the sealed exit leading toward Ludus Magnus, the grand gladiator training school. Your guide would illustrate how trainees marched through this path toward the roar of the crowd, blending history, drama, and archaeology in one unforgettable view.

Spot preserved Roman masonry, drainage systems, and original paving, highlighted by soft amber lighting. Photo stops let you capture the tunnel’s depth and texture, a rare chance to stand where emperors once rehearsed their legends.

Morning or late-afternoon slots offer cooler temperatures and fewer crowds underground. Access to the passage will be in small guided groups (up to 8 people), available only on Mondays and Wednesdays.

Once open, the Passage of Commodus will be part of select Colosseum Underground & Arena Floor Guided Tours or “Full Experience” booking organized by Parco Archeologico del Colosseo. These tours combine the arena floor, underground chambers, and the newly restored imperial tunnel, perfect for travelers seeking behind-the-scenes access.

If tunnel access isn’t yet available during your dates, choose from popular alternatives like the Colosseum, Palatine Hill & Roman Forum Access or the Colosseum with Exclusive Arena Floor Guided Tour — both excellent introductions to Rome’s ancient core.
