Actium or Aktion (Ancient Greek: Ἄκτιον) was a town on a promontory in ancient Acarnania at the entrance of the Ambraciot Gulf, off which Octavian gained his celebrated victory, the Battle of Actium, over Antony and Cleopatra, on September 2, 31 BCE. History. Actium belonged originally to the Corinthian colonists of Anactorium, who probably founded the sanctuary of Apollo Actius. This temple was of great antiquity. In the 3rd century BCE it fell to the Acarnanians, who subsequently held their religious summits there.
