Beneath the basilica, the tour takes visitors into the 1st-century excavations—the home of St. Clement, who served as the third pope.

Visitors observe frescoes, mosaics, and architectural features from this period, which highlight the transformation of the site from a private residence to a Christian place of worship. These fascinating mosaics depict scenes from the Bible and saints, demonstrating the artistic style typical of early Christian Rome.
This layered construction provides insight into how faith and architecture evolved amid changing societal attitudes and religious practices during antiquity.
Within the basilica are the relics of St. Catherine of Alexandria, a Christian martyr revered for her wisdom and faith. The tour includes a discussion of her life, emphasizing her importance to the church and her enduring legacy. The relics have been venerated here for centuries, adding a spiritual dimension to the visit.
