About this tour

Step into the heart of Vatican City on a Rome St. Peter’s Basilica and Underground Tombs Tour, where grand architecture and centuries of history meet. Begin in St. Peter’s Square, taking in its ancient Egyptian obelisk and the optical effects designed by Bernini. Then enter the Basilica with an expert guide to explore its intricate mosaics and celebrated Renaissance and Neoclassical works.

Hear how the emblematic church took 150 years to rebuild as you admire its soaring canopy and Michelangelo’s Pietà. The visit continues below ground in the Papal Grottoes, where you’ll discover the tomb of St. Peter, frescoes, and remnants of the original 4th-century Basilica. Headsets help you follow the guide’s commentary throughout the experience.

The tour does not include skip-the-line access, so queues and crowds may occur. Bring your voucher and look for the coordinator holding a red “TIX & TOUR” sign.

How this score is calculated

This score is based on one provider. Viator rates it 4.58 from 19 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.
