Catacomba di San Gennaro

Lonely Planet review

The oldest and most famous of Naples' ancient catacombs, the Catacomba di San Gennaro date to the 2nd century. Originally they belonged to a noble family, but when San Gennaro's body was interred here in the 5th century they became a hotspot for Christian pilgrims. Naples' bishops were also buried here until the 11th century.

Spread over two levels, the catacombs house a mix of tombs, corridors and broad vestibules held up by columns and arches. The crumbling walls are decorated with 2nd-century Christian frescoes and 5th-century mosaics, including the oldest known portrait of San Gennaro.

To reach the catacombs, go through the gates to the left of the Chiesa di Madre di Buon Consiglio; the ticket office is in a small ivy-clad building. Tours (in Italian) last about 45 minutes but only depart if there are more than two people.
