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.
