Start your unforgettable journey at the 12th-century Basilica di San Clemente, where your guide will show you the golden mosaic in the apse and reveal its hidden meanings. Then, descend 14 meters underground to uncover the hidden 4th-century church built atop St. Clement’s home, adorned with early Christian frescoes. Continue deeper underground to explore one of Rome’s best-preserved Mithraic temples, offering a rare glimpse into ancient pagan rituals. Feel the eerie atmosphere and witness an underground river before emerging back into the basilica, reflecting on your journey through both Roman and Christian history.

For those seeking more, opt for an additional visit to the Basilica di Santo Stefano Rotondo, a stunning example of circular architecture. Inside, you'll be mesmerised by vibrant frescoes that line the walls, each depicting dramatic scenes of early Christian martyrs. These powerful images vividly showcase the courage and sacrifices of saints who endured immense trials for their faith. As your guide reveals the stories behind these incredible artworks, you’ll gain profound insight into the devotion and struggles that have shaped Rome’s religious history.

Wow! Just wow!

This is a must see if you are in Rome! It was FASCINATING! Standing on a floor from 329AD - it's mind blowing! It's such a non -descript building from the outside - but inside - wow - just wow!

We loved our guide for our San Clemente! The mosaic work in the basilica was stunning. The history of the underground structure is so well preserved. We would highly recommend this tour.

Excellent tour of St. Clements's Basilica with Tara Bos.

We had a very informative and enjoyable tour with Tara Bos. We learned so much! Although St. Clement's Basilica isn't a major attraction in Rome, Tara made it incredibly interesting and worthwhile.

No clapping please!

The museum and crypt were outstanding as well as the Gregorian cha t concert. I only wish that they had instructed the audience not to clap after each chant- it was very disruptive and spoiled the sacred mood of the chants. Save applause until it is over.

A special guide!!!!!

We visited the Basilica of San Clemente and its basements with Dtt. Lorenzo, an extremely passionate, professional and highly trained archaeologist. Discovering this magical place with him made the experience a continuous wonder. The tour was exhaustive and interesting especially because Lorenzo gave us so many details and curiosities to make us appreciate even more the beauties of this unique church!, you could listen to it for hours and hours! We were enchanted, thank you very much Lorenzo!!! ❤️
