About this tour
Descend beneath Rome's streets to explore San Clemente Basilica, where three distinct historical layers reveal the city's progression from pagan temple to early Christian worship space. This guided tour unpicks centuries of architecture and religious transformation, with optional access to the adjoining Roman houses on Celio hill—complete with original frescoes that survived centuries underground. Choose between the basilica alone or extend your visit to include both sites. Allow 1–3 hours depending on your selection.
Highlights
- Three excavation levels showing pagan, early Christian, and medieval Rome
- Original frescoes in Roman houses, largely intact from antiquity
- Guided interpretation of architectural and religious transition points
- Underground passages and chambers several metres below street level
- Small group or private tour options available
- Headphones provided for clearer guide commentary
- Optional Casa Romana extension on nearby Celio hill
What to expect
You'll meet your guide at the basilica entrance and begin by exploring the upper medieval church, then move into the underground sections. Expect narrow staircases and passages as you descend—the air becomes cooler the deeper you go. Each level reveals distinct periods: a 4th-century Christian basilica, then a 1st-century Roman house with functioning water system and preserved wall paintings. If you've chosen the Casa Romana option, you'll walk to the nearby archaeological site and explore further residential remains with restored domestic scenes. The pace is steady but unhurried, with your guide providing context at key points.
Good to know
Arrive 20 minutes early. Wear shoulders and knees covered (place of worship). Bring layers—underground areas are noticeably cooler. The site involves multiple flights of stairs and confined spaces; not suitable for people with claustrophobia, mobility issues, or pregnancy. Public transport nearby; plan your own transport. No food or drink included.
