city and capital, nomos (department) of Arta, Ipiros (ancient Epirus) region, Greece. It is situated on the left bank of the Arakhthos River north of the Gulf of Arta. The modern city stands on the site of Ambracia, an ancient Corinthian colony and the capital (from 294 BC) of Pyrrhus, king of Epirus. In 189 BC it was destroyed by the Romans. To commemorate his victory (31 BC) over Mark Antony at Actium, Octavian (later Augustus) founded the new town of Nicopolis Actia a few miles away; as a result, Ambracia declined.
