The Cimitero delle Fontanelle, a charnel house located in the crypts of tuff caves in Naples’ Materdei district, holds thousands of human remains, many the victims of Nappoli’s great plague and cholera epidemics. A cult of devotion the skulls lasted from the late 19th to the mid-20th centuries until the Catholic Church ended the practice by closing the cemetery, now open to the public as an historical site.
