San Pietro in Bevagna is on the shore of the Ionian Sea. The Ionian Sea (Mar Ionio) is an elongated embayment of the Mediterranean Sea, south of the Adriatic Sea. It is bounded by southern Italy including Calabria, Sicily, and the Salento peninsula to the west, southern Albania to the north, and the west coast of Greece.

Il mar Ionio è un bacino del mar Mediterraneo, situato tra l’Italia Meridionale (Puglia, Basilicata, Calabria e Sicilia), l’Albania (Canale d’Otranto) e la Grecia (Isole Ionie).

Le principali insenature sono, nella parte italiana, quelle di Taranto, di Squillace, di Catania; nella parte orientale quelle di Arta, di Patrasso, di Corinto, d’Arcadia, di Messenia, di Laconia.

La parte centrale dello Ionio è libera da isole, e queste mancano anche sul lato occidentale (se si escludono piccoli isolotti lungo la costa italiana), mentre sul lato orientale si succedono le Isole Ionie, alcuni isolotti in prossimità del Peloponneso (da Proti a Cervi), Cerigo e Cerigotto.

All major islands in the sea belong to Greece. They are collectively referred to as the Ionian Islands, the major ones being Corfu, Zakynthos, Kephalonia, Ithaca, and Lefkada. There are ferry routes between Patras and Igoumenitsa, Greece, and Brindisi and Ancona, Italy, that cross the east and north of the Ionian Sea, and from Piraeus westward. Calypso Deep, the deepest point in the Mediterranean at −5,267 m, is located in the Ionian Sea, at 36°34′N 21°8′E.

The limits of the Ionian Sea are as follows:

On the North. A line running from the mouth of the Butrinto River (39°44’N) in Albania, to Cape Karagol in Corfu (39°45’N), along the North Coast of Corfu to Cape Kephali (39°45’N) and from thence to Cape Santa Maria di Leuca in Italy.

On the East. From the mouth of the Butrinto River in Albania down the coast of the mainland to Cape Matapan.

On the South. A line from Cape Matapan to Cape Passero, the Southern point of Sicily.

On the West. The East coast of Sicily and the Southeast coast of Italy to Cape Santa Maria di Leuca.
