What to Expect from the Underground Rome Tour

This tour is best described as an adventure beneath Rome’s surface, revealing stories most visitors miss. It begins just a short walk from the Colosseum, in a charming neighborhood that feels worlds away from tourist crowds. You’ll first visit San Pietro in Vincoli, where Michelangelo’s Moses and the chains of St. Peter are kept—an impressive start that combines art, faith, and history in one small church.

From there, the journey leads to Ludus Magnus, the ancient gladiators’ training ground. Here, you’ll see the ruins where these fierce warriors prepared for combat, connected to the Colosseum via secret tunnels. The site’s hauntingly preserved columns and underground passages take you back to a time when Rome’s amphitheaters roared with life.

The core of the tour is the Basilica of San Clemente, a truly layered treasure trove. As you descend through its three underground levels, you’ll move through:

• The 12th-century basilica with dazzling mosaics
• A more austere 4th-century church buried beneath
• A first-century Roman house with frescoes and intriguing artifacts
• The Mithraeum, an ancient pagan temple where secret cult rites were celebrated

Our reviewer noted that “San Clemente is a place where you can literally touch the layers of Rome’s history,” emphasizing how tangible and immersive the experience can be.

Guided or Self-Guided? Your Options

The tour is flexible, offering both a Private Guided Tour and an Audio Guided Tour:

From the review, travelers praised guides for professionalism and clarity, with one describing a guide as very attentive and knowledgeable.

• The Audio Guided Tour allows you to explore independently, using an app available in several languages. You’ll get access to the same sites, with the freedom to proceed at your own pace. It’s great for travelers who prefer flexibility or want to spend more time at particular spots.

Both options include all entrance tickets, access to underground levels**, and, in the case of the audio tour, headphones are recommended for best audio clarity.
