Entry to the excavations, guide and headsets are included at €59 per person, tips are not. Steps and uneven ground throughout. ## 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. ## Key facts - Price: from €59 per person - Duration: 1h 30m - Rating: 4.92/5 from 182 reviews (collected from Guidekin & Viator & Tripadvisor) - Free cancellation (see policy below) - Operator: EcoArt Travel ## 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.
