What Makes This Tour Stand Out

When you look at what this tour offers, it’s clear that it’s more than just sightseeing. It’s about experiencing Rome’s underground history firsthand. The fact that it’s a small-group tour means you get more attention from your guide, making it a richer, more personalized experience.
The admission included to the archaeological site, which is valued at about 10 euros, provides great value considering the depth of what you’ll see. You’ll explore three levels below the church, revealing a 4th-century basilica, remnants of an ancient pagan temple, and an early Christian site. This layered history is what makes San Clemente such a fascinating window into Rome’s past.
From the reviews, it’s evident that guides like Luca, Gianluca, and Gina are often praised for their knowledge and passion. Many reviews mention their sense of humor and ability to make history come alive, which is key for such an archaeological adventure. One reviewer even called it their “favorite tour,” highlighting how memorable and enjoyable it can be.

The Itinerary in Detail

Start at the Basilica of San Clemente
Your tour begins with a walk into the Basilica of San Clemente itself. This church, dating back to the 12th century, is a stunning structure that combines the medieval with the ancient. Here, the guide will share stories about its construction, art, and significance. Visitors often comment on the beauty of the basilica, but the real magic begins underground.
Exploring the Archaeological Site
Next, the tour dives beneath the basilica, where you’ll descend into the archaeological site. This is where the real treasure lies — three levels below ground. Expect to see the 4th-century basilica, the remains of a pagan temple, and even a Mithraic temple from the 1st century.
One reviewer beautifully summarized this experience: “Being on the floor three levels below ground and learning all the history of how buildings were built on top of each other. The preservation of such old buildings was unbelievable.” It’s like walking through a layered history book, with each level telling a different story.
The Mithraic Temple and Other Remains
The Mithraic temple is a unique highlight. Not every guide takes you this far back, which adds a special touch to the experience. You’ll see well-preserved artifacts and get stories about ancient Roman religions and rituals, making this tour particularly interesting for archaeology enthusiasts.

The Underground Experience
The underground part of the tour, which lasts roughly 10 minutes but feels way more immersive, is a highlight for many. You’ll walk on uneven terrain and climb stairs, so be prepared for some physical activity. But the sense of discovery, of walking through history, makes it worth the effort.
Ending at the Basilica
After exploring the underground, the tour concludes at the basilica, giving you a chance to appreciate its art and architecture at a more relaxed pace. Many reviews appreciate the opportunity to ask questions and take photos, especially since guides like Gina and Priscilla are very accommodating.
