Your tour begins in one of the city’s most compelling Roman catacombs, where persecuted Christians were once buried.
Your guide leads your small group and tells you about the early history of Christianity. Walk along atmospheric tunnels to see frescos and religious depictions.
Next, head to the Capuchin bone crypt, an underground cemetery festooned with the remains of thousands of Capuchin friars. Learn why monks consider the macabre sight life-affirming.
The next stop is Basilica of San Nicola in Carcere, built on the site of Roman temples and markets dating back to the first and fourth centuries BC. See the original structures, which are built into the existing church and left exposed.
Head topside, and bid your guide arrivederci.
