Basilica of San Clemente

Hidden away from the bustling crowds of Rome, the Basilica of San Clemente offers a captivating journey through layers of history. This charming cathedral is cared for with devotion by the Irish Dominicans, whose warm stewardship is evident in every detail. From the moment you step inside, you are welcomed not just into a sacred space, but into a story that spans centuries.

A Descent Through the Ages

What makes San Clemente truly unique is its architectural time travel. After admiring the medieval church with its stunning mosaics and peaceful atmosphere, you have the rare opportunity to venture below. Descend the stairs and you find yourself in the remains of an earlier, fourth-century church—an echo from a time when Christianity was taking root in Rome. The air grows cooler and the sense of antiquity deepens.

The Mysteries of the Mithraeum

But the adventure doesn’t end there. Delve even deeper and you’ll discover a Mithraeum, an underground temple dedicated to Mithras—a god whose mysterious cult was especially popular among Roman soldiers between the first and fourth centuries AD. Here, among ancient brickwork and faded frescoes, you can almost sense the secret rituals that once took place.

The Whispering River Beneath Rome

Perhaps the most magical secret of San Clemente is the subterranean river that flows beneath its foundations. This is the only spot in Rome where you can actually hear the ancient waters trickling by—a haunting, unforgettable reminder of the city’s hidden depths.
