31 Days of Halloween - Fontenelle Ossuary Caves

All over Europe, ossuaries hold the skeletal remains of the long dead, but only in Naples are they expected to produce winning lottery numbers.

The thousands of anonymous plague and cholera dead that fill the Fontenelle Caves outside of Naples were not always renowned for their predictive powers; primarily they were known for being cursed and the caves a haunted place to be avoided. But a 19th century restoration project brought the living into close quarters with the dead and created a kind of charming, if macabre, ‘cult of the dead’. The trapped souls of the long dead were consulted and conversed with, the skulls cleaned and named, wishes, prayers and eventually, requests for winning lotto numbers placed on rolls of paper lovingly inserted into the empty eye sockets.

The success rate of the lotto-number predicting skulls is unknown, but if you would like to try your luck, the Fontenelle ossuary caves are now open by reservation.
