Exploring Rome’s Hidden Depths: The Underground Rome Tour of St. Clement and Celian Houses

If you’re looking to see a different side of Rome beyond the usual panoramic sights, a visit to the underground layers of the city offers a fascinating perspective. This Underground Rome Tour focusing on St. Clement and the Celian Houses is highly recommended for those curious about the city’s lesser-seen history. It’s especially appealing if you’re interested in uncovering the stories beneath the bustling streets and exploring the ancient structures that have survived beneath modern life.
What we particularly like about this tour is how it combines deep historical insight with a personal touch through a private guide. You’ll get to walk through a labyrinth of underground chambers, houses, and ruins that are often missed by traditional sightseeing tours. The tour also covers not just one, but two key sites—the Basilica of San Clemente and the church of Santi Giovanni e Paolo—which gives you a richer picture of Rome’s layered past.
One thing to keep in mind is that this tour involves some narrow, underground spaces. For those who are claustrophobic or have mobility issues, this could be a bit challenging. Tickets are an extra cost, and the tour itself doesn’t include transportation or entry fees, so budget accordingly. This experience is ideal for history buffs, curious travelers, or anyone eager to see Rome from an underground perspective, and it’s best suited for those comfortable with a moderate physical activity level.

A Close Look at the Underground Rome Tour

What’s Included in the Tour
This private tour, priced at around $296 per person, is valued for its exclusivity and depth. The guide is a professional who will tailor the experience to your group, allowing you to learn more than you might on a big group tour. You’ll have the chance to explore a complex of tunnels, ancient houses, and underground chambers that lie beneath Rome’s streets. While the price does not include admission tickets—they are paid separately—you’ll find that these fees are quite reasonable, especially given the rich sights you’ll see.
How the Tour Is Structured
The itinerary is carefully designed to balance historical significance with immersive exploration. It starts at the Basilica of Santi Giovanni e Paolo on the Celian Hill, one of Rome’s ancient Seven Hills. Here, you’ll discover underground Roman houses that tell stories of high and middle-class residents—an intimate peek into Roman daily life centuries ago. The tour spends about 45 minutes here, where you’ll learn about the history of the site and its connection to the city’s past.
Next, you’ll visit the Caelian Hill, a relatively quiet spot compared to the busy center of Rome. This area was once surrounded by aqueducts, temples, and residences of wealthier Roman citizens. Here, you’ll see the underground house of John and Paul, giving you a sense of what life was like for Roman elites.
The highlight of the tour is the Basilica of San Clemente, a marvel with multiple layers of history. Built on top of an ancient Roman house, this church features frescoed walls and underground excavations that reveal structures dating back to the Roman Empire. The guide’s insights turn what might be just a church into a vivid storybook of Rome’s layered history.

The Experience of Exploring Below Ground
Walking through narrow tunnels, ancient tombs, and underground chambers provides a unique sensory experience. You’ll see abandoned shops and homes, including houses of Roman senators, which are rarely accessible in other tours. The sensation of being below the vibrant streets above gives you a tangible connection to Rome’s layered history.
However, it’s worth noting that some spaces can be quite confined. If you’re strongly claustrophobic or have mobility issues, this aspect might be uncomfortable. The tour involves moderate physical activity, including walking and navigating uneven surfaces. The guide will do their best to accommodate, but it’s good to be prepared.
Price and Value
While $296 might seem steep at first glance, consider what’s included: a private guide, personalized attention, and access to exclusive underground sites. Entrance fees are separate, but they remain reasonable—about 30 euros for adults and 18 for children at the Basilica of San Clemente, with additional charges for the other sites.
Many reviewers express satisfaction with the value for money, especially because the guide’s expertise enhances the experience. One reviewer noted, “The 3-hour tour felt like one hour,” which is a good sign of engaging storytelling.
