Greet your guide and small group at the Basilica di San Clemente al Laterano, a beautiful Romanesque church. Descend 60 feet (18 meters) below the ground to see the layers that lie beneath: a 4th-century church and an ancient Roman house.
Hop aboard your comfortable vehicle for the short journey to the Catacombs of Domitilla, a maze of tunnels where ancient Christians buried their dead, which wind underground for 11 miles (18 kilometers). See a 4th-century underground basilica and early Christian wall paintings, and learn about early Christian life.
Finally, walk on ancient Rome’s most famous road, the Ancient Appian Way (Via Appia Antica).
