You step off a sunlit Roman street and descend: cool stone replaces traffic noise, and the city’s layers fold like pages beneath your feet. The tour begins before San Clemente’s basilica, where a single site compresses a Roman house, a Mithraeum and an early Christian church into three living levels. Your guide lights the past with measured detail as you move through low vaults, narrow staircases and chapels that still hold the hush of centuries.
