The modern name of "Filicudi" is a corruption of the ancient Greek name for the island, Phoenicusa (Phoenician island). The island, like the other Aeolian Islands, was settled since the Neolithic Age, around 3000 BCE. As evidenced by archaeological findings, the island was occupied by a new people during the Bronze Age. The island was uninhabited for many centuries until occupied by the Greeks. Roman and Byzantine remains can also be found on the island.
