Luca, our guide, was great! He is very knowledgeable on San Clemente and lead a very informative tour. I learned more from him than I would have just visiting without a guide. The structure is remarkable and it's hard to wrap your head around the history. Truly amazing. I highly recommend this tour!

Our tour of San Clemente with Gianluca was absolutely exceptional. He is the kind of guide who elevates the entire experience from “interesting” to truly unforgettable. His charisma, kindness, and professionalism stood out from the very beginning. Gianluca explained every detail with clarity and passion, offering deep historical insight while keeping the atmosphere light, engaging, and fun. He was attentive to the group, made sure everyone was following along, and delivered each part of the itinerary with expertise and enthusiasm. We learned so much, we laughed, and we genuinely enjoyed every moment. It’s rare to find a guide who combines knowledge, storytelling talent, and such warm personality.

Jessica_G, Oct 2025
San Clemente is a beautiful basilica with so much history and beautiful art. There is a fantastic level from the 4th century below the church, and yet another one below that from the first century. An Italian friend had suggested we go, and I am so grateful for her advice. There are frescoes, inscriptions, original floors, and so much to see. Our guide, Gianlucca, was awesome--fulll of knowledge, energy, and humor.

Nice Tour, but this could be done on your own.

Dana_H, Jun 2025
Tour was informative and on time, with small group. The tour guide was Luca who was awesome. If we were to do it over, we could have purchased tickets and with a written history done it on our own quicker. If you like a ton of information, you would enjoy this tour.

An incredible tour of a fascinating, must-visit Roman site. My daughters both love Roman history, and we all absolutely adored this tour and learned so much! This is a fantastic tour to take, as it is lesser known and truly makes for a memorable stop in this beautiful city. Our guide, Gianluca, was so friendly, knowledgeable, and funny. Highly recommend!

Tyler_W, Dec 2024
Took this as our first tour of Rome with my wife and daughter (9). Ursus was our guide and really made the history come alive. There was only 4 of us in our group and there was very few people at the entire site so it felt like we had our own personalized tour. Very cool to go down through 3 layers of history and see incredible works of art up close and personal. Highly recommend
