Nicopolis or Actia Nicopolis was the capital city of the Roman province of Epirus Vetus. It was located in the western part of the modern state of Greece. The city was founded in 29 BC by Caesar Augustus in commemoration of his victory in 31 BC over Antony and Cleopatra at the Battle of Actium nearby. It was soon made the major city of the wider region of Epirus. Many impressive ruins of the ancient city may be visited today.
