Live the excitement of gradually exploring the different structures built on top of each other during the centuries on your way up to the surface. Cross three layers of history and earth and touch the waters of an underground river.

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.

Wow! Just wow!
Published on Nov, 2024
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!
A quiet beautiful gem!
Published on Oct, 2023
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.
Published on May, 2023
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!
Published on May, 2023
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.
Nice tour with Giovanni
