The Catacombs of Saint Callixtus


Built in the 2nd century, the Catacombs of Saint Callixtus contain dozens of martyrs, sixteen popes, and countless Christians over a 33 acres within 5 levels of 12 miles of tunnels.

We took a cab from the Spanish Steps which was about a 20-25 minute ride.  There is a walking tour of the grounds, and another tour of the catacombs, or you can combine the two.

There is no photography allowed in the crypts, however more information can be found here, with photos.

Below are the grounds at Saint Callixtus.
