The Catacombs of San Gennaro are the largest in Southern Italy, extending over an area of about 5800 square meters on two levels, excavated in the tuff of the hill of Capodimonte to accommodate underground hypogea, commonly called tombs. The first nucleus of burials dates back to a noble family, of which you can see, even today, the frescoes. Around the fifth century A.D. the tombs increased because many faithful wanted to be buried next to San Gennaro, the patron saint of Naples, whose translation of the body at the catacombs was commissioned by the bishop of Naples. In addition to being a cemetery, the catacombs also became a place of prayer, so much so that real basilicas were founded.
