Key Roman Church Tour!

Karen_T, Oct 2025
For church lovers in Rome, this tour should be the first thing they do! I gained so much new information from our excellent guide, Francesca. All the churches I visited after the tour were more meaningful because of what I learned on this tour. Excellent!

Response from Host, Oct 2025

Thank you so much for your review, we are glad to hear that you have enjoyed our Underground Temples of St. Clement's Basilica tour :)

Amazed at “depth” of history

Valerie_R, Oct 2025
Your website explains it perfectly. It’s tight in places, and it’s deep. Loved st. Clemente history.

Response from Host, Oct 2025

Thank you, we are glad to hear that you enjoyed our St. Clement's basilica tour :)

Interesting experience underground

Marsha_M, Sep 2025
Interesting perspective on the lower levels beneath Rome. Chance to hear about snd view how people lived centuries ago. I think other people I know were able to go deeper than our guide offered.

Response from Host, Sep 2025

We appreciate hearing that you enjoyed our St. Clement's Basilica guided tour!

Excellent private tour

Robin_L, May 2025
Excellent tour. We booked a private tour because we anticipated having questions. Ernesto was very knowledgeable. We were most interested in the Mithras temple.

Time Changed Before Tour

Richard_K, Oct 2024
Knowing our schedule that day, we scheduled a 4:00 PM tour. A few days before the tour, I got a message asking if I could switch to 3:00 PM. I responded back that it would be tough, but I would try. Between our schedule and the large volume of traffic, we could not make the revised time slot they switched us to, so we arrived 15 minutes late missing the tour. At least the attendant let us in without additional charge. We tried checking with the various tour groups going through at that time to see if we could meet up but were not successful so we toured the Basilica ourselves as best we could. Later that day I did see that the tour guide did try to reach us to see where we were, but my mobile phone was not operative so I did not see that until later that night.

Response from Host, Nov 2024

Good morning, we are very sorry you were not able to find the meeting point and therefore could not attend the tour, we understand how disappointing that is! However, we would like to clarify that it appears that you unfortunately went directly to the Basilica itself and not to the meeting point, where we waited for you even after the group departed. Furthermore please note that we had tried to reach out to you multiple times by messages and calls to see if you needed any help, however we had not received any response. If you wish to discuss your experience further, please don’t hesitate to reach out to us directly at info@touriks.com.

San Clemente is a beautiful church with an amazing underground. The guide was exceptional. I was very impressed with his knowledge.

Great experience underground!

Julie_K, Oct 2023
We had a very personal tour of the underground temple of the Basilica. We learned a lot and it was much better than trying on our own!

Response from Host, Oct 2023

Thank you so much for taking the time to share your thoughts. We are glad you enjoyed this experience with us :)

Fantastic guide and amazing experience

Jeremy_R, Jul 2023
St. Clement's Basilica is a hidden gem, and much more accessible than many of the over-the-top sites around Rome. And the guide's enthusiasm for the the history was genuine and infectioous.

This is a hidden gem for history buffs!

Steven_B, Jun 2023
To see that many layers of Roman history in one place was amazing. To be able to see the changes in architecture over the span of thousands of years was amazing!!

Incredible!

Michael_L, Jun 2022
Daniele V is an incredible guide at this amazing historic site. Daniele’s passion, enthusiasm and knowledge bring the site to life. It is clear that Daniele loves what he does! Our 25 year old son who travelled to be with us and is not as ‘into’ history as ourselves was transfixed! Thank you for being our guide to this wonderful piece of history - an absolute highlight of our trip to Rome!
