This is the best tour to see many of Rome’s hidden underground gems beginning with the Basilica di San Clemente  (the Church of St Clement) whose structure dates all the way back to ancient Rome. The church is a perfect example of the layers of the city with the 11th century church sitting on top of a 4th century AD basilica, on top of the home of a Roman nobleman, destroyed in 64AD in the great fire of Rome. 

The next stop is the crypt of the Capuchin Friars in the center of Rome.  Here you will see how the friars decorated their crypts with the bones of over 3000 deceased friars.  From the crypt to the catacombs, your driver takes you to the Catacombs of San Callisto, a maze of underground burial tunnels dating back to the early 3rd century AD.
