Coreno Ausonio

Coreno Ausonio is a "comune" (municipality) in the Province of Frosinone in the Italian region Lazio, located about southeast of Rome and about southeast of Frosinone at the foot of Monte Maio, in the Monti Aurunci.
It includes an ancient carved grotto, the "Grotta delle Fate" ("Fairies' Grotto", 8th century BC), likely a tomb of one of the Osco-Sabellian tribes that lived here at the time.
