Get below the surface of modern Rome with an in-depth tour of the Basilica of San Clemente. See how excavations revealed hidden layers underneath the church.
Enjoy skip-the-line entry with your guide and begin in the 12th-century church at street level. Admire the gorgeous 13th-century mosaics in the apse of the basilica as well as the floor. Learn about the Schola Cantorum, which includes some elements of the earlier basilica, before descending the stairs.
See what remains of the 4th-century basilica, including the former central nave and aisles, as you learn about the saints shown in the frescoes on this level—San Clemente and Sant'Alessio (Alexius).
Continue deeper under the basilica to see the remains of a 3rd-century Mithraic altar in a small temple room. Visit the very lowest level under the church to see part of a 1st-century Roman home.
Then move on to the Santi Quattro Coronati Church, built in the 4th-century, and was built in tribute to the four Roman soldiers who were executed for refusing to adore Esculapio. Visit the Oratorio di San Silvestro, with frescoes dating back to the 13th century and show some episodes from the legend of Costantino.
