About 1.5 hours
San Clemente Basilica, Via Labicana
Small group
Mobile ticket
Overview
This is our small-group visit to the layers beneath San Clemente Basilica. With fewer people, you move at a slower pace through the narrow passages and spend more time in the 1st-century Roman level and the Mithraeum.
Your guide explains how Rome’s ground level rose over the centuries, burying whole buildings, and why this site is one of the clearest places in the city to see that history layer by layer.
Highlights
Small group, so there is time for questions
Extra time in the 1st-century Roman rooms
The Mithraeum, with its altar to Mithras
The 4th-century basilica and its frescoes
The sound of an underground stream beneath the city
