The Catacombs of San Gennaro are a vast early Christian burial complex carved into the tufa beneath Naples’ Capodimonte hill. Their two levels of broad, high-ceilinged galleries feel surprisingly monumental, with painted tombs and rows of burial niches opening off the passages.
Burials began here around the second century AD, and the site grew from a family tomb into a Christian cemetery. In the fifth century, the remains of San Gennaro, Naples’ patron saint, were brought here, turning his tomb into a place of pilgrimage. Frescoes spanning several centuries include early Christian imagery and a portrait of the saint, offering a glimpse into the religious life of the ancient city.
A guided tour brings the art and architecture into focus, from simple loculi to elaborate family tombs and underground basilicas. The catacombs also make a rewarding pairing with the Capodimonte Museum and park uphill, or with a walk through the historic Sanità neighbourhood below.
Check tour times and book ahead during busy periods. Wear comfortable shoes for uneven surfaces and steps, and bring a light layer: the galleries can feel cool even when Naples is hot. Buses and taxis serve the area, though walking from the city centre involves an uphill climb.
