The Callixtus Catacombs

Just outside Rome on the Via Appia are the Catacombs of Callixtus, which served as the final resting place for popes in particular, and are said to have buried no fewer than 16 popes, as well as St Cecilia, patron saint of music and the blind. However, she was later moved to her own church in Trastevere.

The Callixtus Catacombs are among the earliest Christian burial sites, and it was here that services were held and communion celebrated in special underground chambers. Take the tour underground with the monks who act as guides. There is not much space on the trail system, so the tour is not recommended for visitors who suffer from claustrophobia.
