Between catacombs and ancient quarries, in the largest underground of Rome

Discover Rome’s Hidden Underworld: From Ancient Quarries to Catacombs

Imagine walking beneath Rome’s bustling streets into a landscape carved out over 2,000 years ago. For just $112.75 per person, you can spend about two and a half hours exploring Rome’s largest underground, where history whispers from every chisel mark and shadowy corner. Guided by passionate experts, you’ll venture through ancient Roman quarries, catacombs, a World War II mushroom farm, and a Mithraeum, learning how these subterranean spaces connect us to the city’s earliest days and its lesser-known stories.

Two things we particularly love about this tour are its authentic focus on real archaeology—not commercialized tourist fluff—and the chance to experience Rome’s underground temperature, which stays around 16°C (about 60°F). That provides a welcome break from the summer heat above ground. One possible consideration? The walk involves some distance and dark, damp spaces, so bringing a jumper and being prepared for uneven, sometimes slippery terrain will make the experience more comfortable.

This tour is perfect for travelers who crave a deep dive into Rome’s underground secrets and enjoy stories beyond the typical tourist spots. If you’re eager for knowledgeable guides, stunning historical revelations, and a hands-on experience, this outing will satisfy your curiosity without the crowds.

Exploring Rome’s Underground: A 2.5-Hour Journey into History

When we first heard about this tour, we were intrigued by the promise of over 35 kilometers of underground tunnels—a real labyrinth beneath Rome’s streets. What makes this experience stand out is its blend of ancient Roman engineering, early Christian remains, and World War II history. It’s a layered look at the city’s hidden fabric, far from the crowded Vatican or Colosseum.

The adventure begins in Caffarella Park, a peaceful green space that offers a gentle walk of about a kilometer. It’s the perfect way to transition from Rome’s busy streets into the quiet, shadowy underground. As you walk, your guide will share stories about the Roman slaves who carved these tunnels and the artisans who built the city’s foundations.

The Roman Quarries and Catacombs

Your first stop is the ancient Roman quarry system, where the city’s stones were extracted and transported. These tunnels, often reused in later centuries, reveal the massive scale of Roman engineering. The walls still bear chisel marks that hint at the backbreaking labor of slaves, often working in exchange for their freedom—or their lives. As your guide explains, “this underground world still writes its story in every wrinkle of the walls and every sign on the stones.”

From there, you’ll enter the catacombs, a sprawling network of tunnels used by early Christians. You’ll experience the darkness and coolness firsthand, crossing narrow passages where loved ones were laid to rest for thousands of years. One reviewer highlights how “the work that archaeologists are doing here is remarkable,” and that the site feels like a living museum, with ongoing discoveries adding layers of intrigue.

WWII Mushroom Farm and the Mithraeum

The journey continues into a World War II mushroom farm, a surprisingly recent reuse of the underground tunnels. This echoes how Rome’s underground spaces have been repurposed across centuries, reflecting the city’s resilience and adaptability.

Next, you’ll visit the Mithraeum, an ancient pagan temple dedicated to Mithras, a figure whose worship influenced early Christianity. “You cannot visit Rome without seeing this,” one enthusiastic reviewer insists, as it offers a glimpse into religions that shaped the roots of Christian faith. The dim lighting and historic artifacts make it a captivating stop that connects faith, culture, and history.

What to Expect During the Tour

The tour is designed to be engaging and accessible while respecting the sensitive nature of these ancient spaces. Expect to receive a headlamp and helmet, crucial tools for navigating the damp, dark tunnels. You’ll walk more than a mile in total, encountering niches, inscriptions, and relics along the way.

The group size is capped at 10, allowing for an intimate experience where questions are encouraged, and guides can share detailed stories. Since the tour lasts about 2 hours and 30 minutes, you should wear comfortable shoes and be prepared for occasional uneven terrain.

One highlight from reviews is how knowledgeable guides like Riccardo and Giuseppe make the stories come alive, explaining the labor of slaves, early Christian burial practices, and the significance of pagan temples with a mix of passion and clarity.

Exploring the Underground
