The Augusta Bay is located on the east coast of Sicily, Italy, about 270 nm south-southeast of Naples.
The modern Capo di Santa Croce was called Xiphonian Promontory (Ancient Greek: τὸ τῆς Ξ̔ιφωνίας ἀκρωτήριο).
Diodorus Siculus mentions that the Carthaginian fleet (263 B.C.)
Stephanus of Byzantium wrote about a town there which was called Xiphonia (Ξιφωνία),[2] but most probably he made a mistake, since no other known ancient author mentioned it.
[3] It is the location of the Augusta Bay Port Facility which supports the Sixth Fleet of the US Navy.
