Rome San Clemente Basilica and Underground Excavations Tour

Step beneath the streets of Rome to uncover the remarkable layers of San Clemente Basilica. On this guided visit, a licensed guide leads you from the medieval basilica down to a 4th-century church, then farther into ancient Roman rooms and a Mithraeum. Each level reveals a different chapter of the city’s past, making this an absorbing way to explore Rome beyond its familiar landmarks. Your reserved time slot includes access to the archaeological excavations and a visit to the basilica. Meet at the entrance on Piazza di San Clemente, arriving at least 15 minutes before the time printed on your ticket; look for the guide holding a Gyash Tours flag. Scaffolding will be present in the upper Basilica until mid-2027. Please note that the underground route involves stairs and is not suitable for wheelchair users or travelers with reduced mobility or difficulty with stairs.
