Catacombe di San Gennaro
These are the most important catacombs in southern Italy due to the length of their use as a burial site and the well-preserved mosaics. In use from the rise of Christianity until the 10th century, they hold the tombs of many bishops including the Basilica di Sant'Agrippino, the 3rd century bishop of Naples.
Nearby is the tomb of San Gennaro, the patron saint of Naples, whose remains were moved here in the 5th century to the Cubicolo di San Gennaro. He was later removed to the Cathedral of Naples.
Catch bus 24 or R4 to Via Capodimonte in the northern hills of Naples, then walk down an alley beside the large church Madre del Buon Consiglio.
