Porto Kagio

Porto Kagio or Porto Káyio (Greek: Πόρτο Κάγιο) is a seaside village on the eastern side of the Mani Peninsula, in the Peloponnese, Greece. Porto Kagio faces a small bay on the Laconian Gulf, and is about three miles north of Cape Matapan, the southernmost tip of mainland Greece.

Some 17th- and 18th-century maps label the village "Maina"—the historical name for the Mani Peninsula—and some authors consider Porto Kagio a possible location for the castle of Grand Magne; medieval portolans mention no such castle there.
