Descend through churches, Roman ruins, and ancient buildings on a two-hour tour of the hidden layers beneath Rome.

About this tour

Step beneath the streets and travel through more than a thousand years of history on this Rome Underground Layers Tour. At the Basilica of San Clemente, each descent reveals a different chapter of the city. Begin in the church built around 800 years ago, then continue to an earlier fourth-century Christian basilica. Below it, explore an ancient Roman house that was later converted into a temple, followed by the remains of a first-century public building. The route also visits a church built over two older structures on the ruins of the Roman Forum. Along the way, learn how repeated floods helped shape Rome’s remarkable underground layers. With entrance tickets included, this two-hour Rome Underground Layers Tour offers a vivid look at the city beneath the city. Meet your guide by the blue octopus on a flag stick, and discover the stories hidden below Rome.

How this score is calculated

This score is based on one provider. Viator rates it 5.00 from 4 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 7.3. Top 31% in Rome means it ranks in the top 31% of tours in Rome by this score.
