Explore St. Clement's hidden underground site and the Catacombs of Domitilla on a small-group tour through Rome's ancient history.

About this tour

Step beneath Rome's busy streets to discover a hidden world of ancient worship and winding burial tunnels. This small-group Rome Catacombs and St. Clement's Underground Tour visits two contrasting sites with a professional guide, bringing the city's layered history into view.

Begin at St. Clement's Basilica, where the route descends 14 meters to the remains of a hidden cult. Then travel beyond the city walls to the Catacombs of Domitilla and explore their maze of underground passages and ancient wall paintings. A maximum of 10 participants keeps the experience intimate, while sterilized headsets help you hear the guide clearly. Entrance and transport fees, on-site assistance, and a luggage deposit during the tour are included.

How this score is calculated

This score is based on one provider. Viator rates it 4.81 from 32 reviews. We place that rating among all Viator ratings and weight it by its review count. If the tour is found on another provider later, both ratings are combined.

How the score works and rating distribution in Rome
  • Each provider rating is turned into a percentile: the share of that provider's ratings it beats, weighted by review counts.
  • Listings on different providers are combined in proportion to their review counts.
  • Tours with few reviews are pulled toward the average until more reviews come in, so a handful of perfect reviews can't top the list.
  • The result is shown from 0 to 10: this tour scores 7.1.
