About the tour

Just a stone’s throw from the Colosseum, you will find one of Rome’s hidden gems, the 12th-century Basilica and the archeological site of San Clemente. Visit this incredible place and navigate three underground levels which uncover over 2,000 years of history. The Basilica reveals a sparkling gold mosaic in the central nave. What lies beneath the Basilica remained a secret until 1860 when a flood led an Irish Dominican Roman Catholic priest and archaeologist to discover the levels beneath.

Today, the excavations are still not complete but you can descend 100 feet underground. At the first level is a 4th-century Basilica, which was long forgotten after the construction of the 12th-century Basilica above. Further down are the remains of an ancient pagan Mithraic temple, complete with an altar. Past the temple are the ruins of ancient Roman homes. All of this is incredibly preserved and was painstakingly excavated. At the lowest level, discover the underground spring which caused the chaos that led to the underground discovery.

Unforgettable

Our tour of San Clemente with Gianluca was nothing short of extraordinary Hes the kind of guide who transforms a simple visit into a onceinalifetime experience elevating everything from interesting to truly unforgettable His charisma kindness and professionalism were evident from the very first moment San Clemente itself is a place every visitor must see in Rome Nowhere else in the city layers history so vividly a 12thcentury basilica built over a 4thcentury church resting atop a 1stcentury Roman structure Walking through it feels like descending through time literally stepping deeper and deeper into the past Its one of the rare places where you dont just learn history you feel it Gianluca brought all of this to life with clarity passion and a gift for storytelling He explained every detail offered profound historical insights and kept the entire atmosphere light engaging and fun He was incredibly attentive always making sure the whole group was following along and delivered every moment of the itinerary with enthusiasm and expertise We learned so much laughed a lot and genuinely enjoyed every second Its rare to find a guide who blends knowledge personality and storytelling talent so perfectly Visiting San Clemente is already a must but visiting with Gianluca makes it unforgettable We absolutely loved it highly recommended
