Gaiola Island, Posillipo, Naples, Italy

History
The island takes its name from the cavities that dot the coast of Posillipo (from the Latin cavea, "little cave", and then through the dialect "Caviola"). Originally, the small island was known as Euplea, protector of safe navigation, and was the site of a small temple.
The island is very close to the coast, reachable with a few strokes of swimming. It is assumed that originally it was nothing more than an extension of the promontory opposite and was artificially separated only at a later time at the behest of Lucullus.
