Portus Julius

Portus Julius (alternatively spelled in the Latin Iulius) was the first harbour specifically constructed to be a base for the Roman western naval fleet, the classis Misenensis. The port was located near Baiae and protected by the Misenum peninsula at the north-western end of the Gulf of Naples. Portus Julius was named in honour of Octavian's great-uncle and adoptive father, Julius Caesar and the Julian clan.
