Gulf of the Ionian Sea, on the coast of the southwestern Peloponnese , Greece.
On the west side of the gulf is the port of Koróni, originally settled by Argives after the First Messenian War (с 735–715 BC) and reoccupied during the Middle Ages by refugees from the north. The French landed at the Gulf of Messenia in 1828 during the War of Greek Independence to drive the Turks from the Peloponnese.
