Ventotene lies in the Tyrrhenian Sea off the west coast of Italy . Unlike its more frantic ( by Italian standards ) and popular southern neighbors , Ischia and Capri , Ventotene has barely been touched by international tourism . Roman emperors found the island 's climate perfect for banished criminals . Its lush and mostly undisturbed aquatic life makes it attractive to recreational divers .
