Discover Rome's hidden underground world with this small-group tour exploring ancient shrines, dwellings, and fascinating layers of history beneath the city streets.
Walking beneath Rome’s bustling streets reveals a secret world most visitors never see. This Ultimate Underground Tour offers an intimate look into the city’s subterranean layers, combining history, archaeology, and storytelling in a way that feels both authentic and engaging. Guided by a passionate historian and theologian, the experience promises an immersive journey through time that reveals Rome’s lesser-known but equally captivating past.
One of the standout features we love about this tour is the small-group format, which means more personalized attention, better opportunities for questions, and a more relaxed atmosphere. The tour also includes entry tickets to some of Rome’s most intriguing underground sites, ensuring a hassle-free experience. However, for travelers relying on public transport or with tight schedules, the tour’s starting point and timing might require a bit of planning.
This experience is best suited for history buffs, curious travelers who enjoy off-the-beaten-path discoveries, and those who want to see Rome from a different perspective—beneath the surface. It’s an excellent way to add depth (literally and figuratively) to your Roman adventure.

One of the most compelling aspects of this tour is the chance to see ancient Roman homes and shrines that have survived beneath the city streets. The first stop, Case Romane del Celio, offers a window into daily Roman life through remarkably preserved dwellings. These ancient houses feature intricate frescoes, mosaics, and rooms that feel like they’ve been frozen in time. We loved the way these remains give us a firsthand look at Roman craftsmanship and domestic architecture—something you won’t find in typical guidebooks or on the surface.
The guide, whose background as both a theologian and historian shines through, shared fascinating details about the homes’ layout and the social status they represented. As one reviewer noted, “Justin was a very good guide, easy to understand, and we learned a huge amount of Roman history during the tour.” This highlights how much a knowledgeable guide can elevate the experience, making the past come alive through storytelling.

The second major highlight is Basilica di San Clemente, a site that truly encapsulates Rome’s layered history. Descending into this basilica feels like peeling back the pages of a history book. Built on top of a 4th-century church, which itself was constructed atop an ancient Roman house, it’s a multi-tiered testament to the city’s constantly evolving religious and cultural landscape.
What makes San Clemente especially intriguing is its underground layers, revealing everything from Roman pagan cult practices, including the Mithras temple, to early Christian worship. The site provides a rare glimpse of exotic religious traditions before Christianity took hold, making it a must-see for anyone interested in religious history or archaeology. The guide explained how different architectural styles and relics from various periods converge here, creating a complex mosaic of Rome’s spiritual past.
Reviewers have commented on the “exotic Persian cult of Mithras” within this site, emphasizing the sense of discovery. The underground passages and frescoes are not just visually stunning, but they also tell stories of ancient beliefs that shaped Rome’s spiritual landscape.

Starting Point & Timing:
The tour begins promptly at 9:45 am from Piazza di Santissimi Giovanni e Paolo. It concludes at the Basilica of San Clemente, so you’re right in the heart of the city’s historic core at the end. The duration of 2 to 3 hours makes it manageable even for those with a busy schedule.
Group Size & Atmosphere:
With a maximum of 8 travelers, this tour offers a very intimate setting. This small group size enhances the experience, allowing for more interaction and questions. It’s ideal for those who prefer a more personalized tour rather than large crowds.

Accessibility & Participation:
Most travelers can participate, and the tour is near public transportation. However, some sections involve descending stairs and walking through uneven underground passages, so comfortable footwear is recommended.

What truly sets this tour apart is the expert narration and storytelling. Our guide, with a background in theology and history, didn’t just read facts—he painted vivid pictures of what life was like in ancient Rome, weaving stories of everyday citizens, religious rites, and architectural wonders. This storytelling approach keeps the experience lively and memorable.
The underground shrines and homes are visually stunning; the frescoes and mosaics have been remarkably preserved, allowing you to appreciate Roman artistry firsthand. One reviewer mentioned how they appreciated the way the guide explained the significance of relics and religious symbols, making the sites come alive.
Another highlight is the fusion of architectural styles—from pagan temples to early Christian basilicas—that showcase Rome’s layered history. As you walk through these underground corridors, you get a feeling of walking through time itself, with each level revealing a different chapter of Roman life.

While many visitors flock to the Colosseum and Vatican Museums, this underground tour offers a distinctly authentic, less touristy experience. It’s like uncovering Rome’s secret stories that aren’t often told, adding depth to your understanding of the Eternal City. For those who love digging a little deeper—literally—this tour provides a rare chance to see the city’s hidden past.
The small group format means you can ask detailed questions, whether about Roman architecture, ancient religious practices, or the stories behind specific frescoes. This interactive element makes the experience both educational and engaging, especially for those who enjoy absorbing history through storytelling.

This experience is ideal for history lovers, archaeology enthusiasts, and curious travelers eager to see a different side of Rome. It suits those who want a more personalized, in-depth exploration rather than the typical tourist circuit. It’s also perfect for visitors with a keen interest in religious history or those who appreciate well-preserved ancient sites.
On the practical side, the tour’s timing and location make it easy to incorporate into a full day of sightseeing, especially if you want to balance surface-level landmarks with underground marvels.
