About the tour

Discover one of Rome’s hidden gems on a guided tour of the Basilica and archaeological site of San Clemente. Explore three underground levels and uncover over 2,000 years of history beneath the city streets.

Visit the beautiful 12th-century Basilica before descending to the remains of a forgotten 4th-century church and an ancient Mithraic temple with its original altar. Learn how these fascinating underground ruins were discovered in 1860 after a flood led an Irish Dominican priest and archaeologist to uncover the hidden levels below.

At the deepest level, see the underground spring that caused the discovery and explore the remains of ancient Roman homes, carefully excavated and remarkably preserved. A unique experience away from Rome’s more crowded attractions.

Fantastic tour

This is one of the best Hidden Gems in Rome and only a few blocks away from the masses at the Colosseum Gina was an EXCEPTIONAL tour guide and I would readily book tours with her at any historical sites in the city Each layer of this Lasagna Basilica is full of interesting historical artifacts and gives a very unique insight into how the city of Rome evolved over the centuries rebuilding and recycling on top of the ancient structures Highly recommend
