Ancient Nikopolis is located 10km north of the city of Preveza on the national road Preveza - Ioannina. A few kilometers outside Preveza, is the largest ancient city in Greece. Nicopolis was the pride of the Roman Emperor Octavian, the city he built in commemoration of his victory against the allied fleet of Antony and Cleopatra at the naval battle of Actium in 31 BC. A city spread over acres upon acres - so much that you'd have to drive to get from, say, the Conservatory to the Theatre - and whose Byzantine walls go on for miles. The archaeological site, in addition to the Odeon and the Theatre, includes two early Christian basilicas with impressive mosaics, the monument to Augustus and the stadium. Nicopolis - the City of Victory - was founded in 31 BC by Octavian Augustus in honour of his victory over Antony and Cleopatra at the naval battle of Actium. The city developed and flourished both in Roman times, when it had about 300,000 inhabitants, and later during the Early Christian period. The visitor to Ancient Nikopolis is impressed by the large area of the archaeological site, stretching from the Ionian to the Amvrakikos, and the number of preserved monuments scattered over an area of about 1500 acres.
