Which sea is bounded by southern Italy, southern Albania, and western Greece? The Ionian Sea is the Mediterranean sea bounded by southern Italy, southern Albania and western Greece.
It occupies the Mediterranean east of Sicily and southern Italy, west of mainland Greece and the Peloponnese, and south of Albania and the Strait of Otranto region. The sea connects northward with the Adriatic and contains Greece's Ionian Islands, including Corfu, Kefalonia, Zakynthos, Lefkada and Ithaca.
The Ionian has deep historical connections to Greek myth, ancient colonization and Roman history. Odysseus is traditionally associated with Ithaca, while Greek settlers crossed the sea from at least the eighth century BCE to establish colonies in southern Italy. In 31 BCE, the Battle of Actium took place at its northeastern edge.
A notable modern geographic fact is that Calypso Deep lies in the Ionian Sea. At about 5,109 metres, it is recognized as the deepest point in the Mediterranean. The Myrtoan Sea is a neighboring subdivision, not the broader sea described by the question.
