They call it the Campi Flegrei, the Burning Fields, for the copious number of volcanic cauldrons (a super volcano) that are simmering in this area just west of the city. Here, lies the stuff of myths and lore: the so-called home of Vulcan, the Roman god of fire; the river Styx; a birdless lake; an uttering Sibyl and the entrance to Hades. The Campi Flegrei was the backdrop for Virgil’s Aeneid and it secrets a rare geological phenomenon known as bradyseism. Visitors to Naples rarely venture out into the Phlegrean Fields, opting for the more popular and well known sites like Pompeii and Vesuvius. Those who do venture here will find some of these sites eerily quiet, so quiet in fact you may be able to commune with the spirits.
