Formentera is the smaller and more southerly island of the Pityusic Islands group (comprising Ibiza and Formentera, as well as various small islets), which belongs to the Balearic Islands autonomous community (Spain).HistoryThe island's name is usually said to derive from the Latin word frumentarium, meaning "granary". The island was occupied in prehistoric times, going back to 2,000-1,600 BCE. Archaeological sites from that period remain in Ca na Costa, Cap de Barbaria (multiple sites) and Cova des Fum. The island had been occupied by the Carthaginians before passing to the ancient Romans. In succeeding centuries, it passed to the Visigoths, the Byzantines, the Vandals, and the Arabs. In 1109 it was the target of a devastating attack by the Norwegian king Sigurd I at the head of the "Norwegian Crusade". The island was conquered by the Catalans, added to the Crown of Aragon and later became part of the medieval Kingdom of Majorca.
