A Deep Dive into Rome’s Hidden Underground

The Initial Walk through Caffarella Park

Your journey begins in the lush greenery of Caffarella park, a serene spot where you walk about a kilometer. Many reviewers remark on how this peaceful warm-up contrasts with the bustling city above. It’s a chance to stretch your legs, breathe in fresh air, and get into the spirit of exploration. As one visitor noted, it’s “a regenerating walk surrounded by nature,” perfect for clearing your mind before descending into ancient darkness.

Discovering the Roman Quarries

The highlight of the tour is the Roman quarries, a sprawling underground network extending over 35 kilometers (about 21 miles). These tunnels were initially dug to extract the stone used in constructing Rome’s iconic monuments and buildings. What’s captivating is how much of this underground system has been preserved, with chisel marks still visible on the walls, hinting at the toil of ancient slaves.

What you’ll see:
You’ll walk through narrow passages, admire the rough-hewn stones, and witness the marks left behind by those who labored here. According to a review, “you can still see the chisel marks of the ancient slaves who dug this place,” which makes the experience feel incredibly tangible. Visitors have described it as a place where “history is written in every wrinkle of the walls.”

Practical info:
Expect a fair amount of walking in uneven, damp conditions. It’s a cool environment, so bringing a light jacket or jumper is advised — as one traveler explained, “it was much colder and very damp inside so bring a jumper.”

Crossing the Catacombs

Next, the tour dips into the catacomb tunnels, where early Christians buried their loved ones. These passages stretch for dozens of kilometers underground, with some chambers decorated with faint frescoes or inscriptions. A reviewer called the visit to the catacombs “stupendous,” highlighting how it brings to life the spiritual practices of early Rome.

What you’ll experience:
Walking through dimly lit corridors, listening to stories of Christian martyrs, and peering into burial niches. It’s a humbling experience that offers insight into early Christian community life, often concealed beneath the city’s surface.

Exploring the Mithraeum and WWII Mushroom Farm

The journey continues into an ancient Mithraeum, a pagan temple dedicated to Mithras, a god linked to mystery religions that predate Christianity. This site demonstrates the religious diversity of ancient Rome and the roots of Christianity, which eventually supplanted such pagan cults.

Beyond that lies a surprisingly modern twist: a WWII mushroom farm where Roman tunnels found a new purpose in the last century. Visitors are often intrigued to find this unexpected connection between ancient and recent history. The tour guides share stories about how these tunnels were repurposed, giving a layered sense of continuity beneath Rome.

The Final Stop: The Pagan Temple

The tour culminates in a pagan temple (Mithraeum), where you’re equipped with a headlamp, helmet, and a sense of adventure. Stumbling through over a mile of underground corridors, you’ll get a real feel for the underground worlds that housed both spiritual and practical functions over centuries.

What visitors say:
Many reviewers, like Diana, mention how “the guide showed us how the ancient Roman slaves had dug out the cave,” and how the environment “was much colder and very damp inside.” The experience feels like a true journey back in time — not just a sightseeing stop, but a tangible connection to Rome’s layered past.
