It was established thousands of years ago. In fact the Ravenna military and trade seaports are pictured in the opposite walls of
S. Apollinare Nuovo, a church built in Ravenna by
Theodoric the Great. In 31 BC, Emperor
Augustus founded near Ravenna the military harbor of Classe. It hosted the second imperial
fleet of the
Roman Empire (according to
Vegetius, Epitome of Military Science fourth book - the first one was located in
Portus Julius near
Capo Miseno near the
Port of Naples) Even after the Empire's decline in the 5th century, the port kept active and entered a further golden age during the Byzantine dominion as the mosaics bear witness. It underwent decline after being flooded by the mud of the rivers and conquered by Venice in the 15th century. In 1738, the Corsini Canal (named after
Pope Clement XII), connecting Ravenna to the sea, started up its activity. The
United States Navy established a
naval air station at Porto Corsini on 24 July 1918 to operate
seaplanes during
World War I. The base closed shortly after the
First Armistice at Compiègne. After World War II a huge petrochemical plant was established, but the
oil crisis of 1973 enhanced its multipurpose trade facilities. In 2021, Ravenna's Port Authority awarded Royal Caribbean Cruise Line to build a two-berth cruise terminal and expected to be completed Spring 2024. ==References==
