Entry to the excavations, guide and headsets are included at €59 per person, tips are not. Steps and uneven ground throughout. In our comparison: #10 of 46 in Catacombs & Underground Rome, by rating weighted by review volume (table below). ## Overview A visit of the 12th century Basilica of San Clemente reveals a gleaming gold mosaic above the central apse. St. Clement's transformed over centuries from a private home that was the site of a secret Christian worship in the first century to an imposing basilica. What laid beneath the Basilica was unknown until 1860, when flooding led an Irish Dominican Roman Catholic priest and archaeologist into the levels beneath the basilica floor. Excavations are ongoing. Today, you can descend up to 100 feet underground over three levels. At the first level we will find a 4th century Basilica, long forgotten after the construction of the 12th century Basilica above. Underneath, find the remains of an ancient pagan Mitraic temple. Lower still, ruins of ancient Roman homes. ## Before you book - Meeting point: Meeting point is near St Clemente… - Entry ticket included: skip the ticket desk - Starts 10:00, 15:00: 2 departures a day - Children from €49: ages 8 to 16 **Pickup:** No hotel pickup: everyone meets at the start point ## Key facts - Price: from €59 per person - Duration: 1h 30m - Rating: 4.92/5 from 187 reviews (collected from Guidekin & Viator & Tripadvisor) - Free cancellation (see policy below) - Likely to sell out - Operator: EcoArt Travel - Group: Shared tour - Guide languages: English - Tickets: Admission included - Start times: 10:00, 15:00 - Booking: Instant confirmation, mobile ticket - Price checked on Viator: 2026-09-25 ## Reviews 4.92 from 187 ratings on Guidekin, Viator & Tripadvisor. 99% of ratings with a star breakdown are 4 or 5 stars: 185 of 187. - 5 stars: 178 (95%) - 4 stars: 7 (4%) - 3 stars: 0 (0%) - 2 stars: 0 (0%) - 1 star: 2 (1%) ### What reviewers say Reviewers praise clear explanations of the basilica's layers and the guides' enthusiasm; some would prefer a quicker visit **Praised:** - Knowledgeable guides who explain the site's history clearly and with humour - Exploring layers of earlier churches and Roman ruins beneath the basilica - Personal attention and patient answers to questions - Cool underground spaces that offer relief from the heat **Complaints:** - Some find the pace comfortable, while others would prefer a quicker visit Written by Guidekin from the 100 most recent English reviews on Viator & Tripadvisor (2024-05-02 to 2026-09-28); last checked 2026-10-03. ## What's included - Expert & Passionate English Speaking Guide - Access to San Clemente Undergrounds - Professional Headsets to hear your guide clearly (when at least 5 guests) - Small group tour (max 15 guests) - Entrance Tickets to the Archeological Site of San Clemente (10 euro value) ## Not included - Gratuities - Hotel Pick-up and Drop-off ## Itinerary 1. **Basilica of San Clemente** (1h 30m; admission included) - Visit of the Basilica of San Clemente in Laterano and the archeological site. 2. **Mitreo di San Clemente** (10m; admission included) - Part of the visit of the archeological site under the Basilica of S.
