Catacombs of San Gennaro



Catacombs of San Gennaro

The Catacombs of San Gennaro, located underground in Naples, represent one of the most significant monuments of ancient Christianity in the city.

The catacomb of S. Gennaro is made up of two non-overlapping levels. The original nucleus can be identified in the use and expansion, which took place between the end of the 2nd and the beginning of the 3rd century, of a so-called “lower vestibule” environment.

From it, in the periods following the 3rd century, the ambulatories of the lower catacomb developed according to a broad and horizontal excavation scheme.

The upper catacomb had various phases of development: it too originated from an ancient tomb that today we call the “upper vestibule”, known essentially for the frescoes on the vault from the end of the 2nd century.
