Explore Vicus Caprarius and the Stadium of Domitian on a guided journey beneath Rome’s famous fountains and piazzas.

About this tour

Beneath Rome’s celebrated fountains and piazzas lies another city, shaped by water, sport, and centuries of history. This 150-minute Rome Underground Tour takes you below street level to explore archaeological sites hidden from view.

Visit Vicus Caprarius, known as the City of Water, and uncover passageways and ruins beneath the area around the Trevi Fountain. Then descend beneath Piazza Navona to the Stadium of Domitian, where as many as 30,000 spectators once gathered. Along the way, an official guide of the City of Rome brings the ancient remains and the role of sport in Roman life into focus. Entrance tickets and a bottle of water are included, and the tour is led in English.

Meet your guide at Via del Corso 230. Underground temperatures are cooler than outside, and if institutional closures affect a site, the visit will be replaced with a similar site of equal interest. Discover a quieter, hidden side of the capital on this Rome Underground Tour.

How this score is calculated

This score is based on one provider. Viator rates it 4.42 from 12 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 6.6.
