The Ionian Sea is an outstretched embayment of the Mediterranean Sea, located towards the south of the Adriatic Sea. It’s bordered by southern Italy including Sicily, Calabria, and the Salento peninsula towards the west, southern Albania towards the north, and west coast of Greece.
All of the major islands within the sea belong to Greece. They are together referred to as the Ionian Islands, the major ones being Zakynthos, Kephalonia, Lefkada, Ithaca, and Corfu. Calypso Deep is the deepest point in the Mediterranean at -17,280 feet; it is located in the Ionian Sea. The sea is one of the largely seismically active areas in the world.
The name Ionian is derived from the Greek language. The etymology isn’t known.
