The Capuchin Crypt (Cripta dei Frati Cappuccini), a series of six small chapels used to bury Capuchin monks who died between 1528 and 1870, ultimately held around 3,700 bodies interred in the crypt’s sacred soil brought directly from Jerusalem. You can walk through the bone chapels to admire the unique decorations created by the skeletal remains of the deceased, said to be a reminder of the fleeting nature of mortality.
The best way to understand the historical and religious context of this remarkable site is to join a small-group crypts and catacombs tour. These tours typically visit the Capuchin Crypt and accompanying museum along with the ancient Roman catacombs under the Basilica of San Clemente with a tour guide. To avoid the daytime crowds, you can also opt for an private tour with exclusive after-hours access to the crypt.
