Lake Averno is the second largest lake in Campania in the province of Naples, in the Campi Flegrei area. It is a lake of very ancient origin, formed in the basin of a now extinct volcano.
Today it is a naturalistic oasis full of charm, but once upon a time the landscape was different. The sulphurous fumes that flowed from the lake prevented the life of the animals. The name of the place derives, in fact, from a-ornos, a place without birds. Dense, nauseating fumes rose from its banks and the hills around were covered with a thick wood of dark trees.
