What To Expect

Basilica of San Clemente

Embark on an unforgettable journey that begins at the breathtaking 12th-century basilica, where your expert guide will unveil the secrets behind the stunning golden mosaic in the apse, highlighting its spiritual significance. From there, descend 14 meters beneath the basilica to uncover the hidden 4th-century underground church, built directly on top of St. Clement's home, the third pope of Rome. Marvel at the early Christian frescoes, which depict the stories of martyrs and the struggles faced by the first Christians.
 Next, continue your descent to uncover one of Rome’s best-preserved Mithraic temples. This ancient treasure offers you a unique glimpse into the mysterious Mithraic cult, which thrived before the rise of Christianity. Let your guide bring this fascinating chapter of Roman history to life as they explain the cult’s intriguing rituals and beliefs. As you explore the site, you'll feel an eerie atmosphere, enhanced by an underground river that adds an element of mystery.
