Explore ancient homes beneath Celio Hill and visit the Basilica of San Clemente on a private, guided journey through underground Rome.

About this tour

Step beneath the streets of Rome to uncover ancient homes, vivid frescoes, and centuries of history on this private underground tour. At Case Romane del Celio, explore Roman houses on Celio Hill and picture daily life in one of the city’s wealthiest neighborhoods 2,000 years ago. Then continue to the Basilica of San Clemente, an early Christian church near the Colosseum and dedicated to Pope St. Clement.

A Blue Badge-certified private guide leads the walking tour and brings these remarkable sites to life. Admission tickets to both locations are included. A one-way transfer from your hotel or accommodation is provided, while hotel pickup and drop-off are available if you select that option. Wear clothing that covers your shoulders and knees, as holy sites enforce a dress code. Book your Rome underground tour to discover a quieter, fascinating side of the Eternal City.

How this score is calculated

This score is based on one provider. Viator rates it 5.00 from 2 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 7.2. Top 40% in Rome means it ranks in the top 40% of tours in Rome by this score.
