Meet your guide in front of St. Clement's Basilica and descend into a mystical underground world of ancient cults and legends. Journey through layers of history, reaching 14 meters below ground, then gradually explore the structures built atop it as you ascend.

At the lowest level, discover the city's best-preserved Mithraic temple and uncover the pagan faith of Ancient Romans before Christianity. Learn about early Christian persecutions and the legend of St. Clement while standing in his first-century home.

Feel the eerie atmosphere and touch an underground stream. Then, explore the remains of the fourth-century Basilica, with its imposing walls and ancient frescoes depicting the lives of martyrs.

Conclude your tour in the stunning twelfth-century Basilica, admiring its golden apse mosaic and hidden symbolism.
