Nikopolis or Nicopolis (it means, the victory city) is probably the largest in size ancient city in Greece, but still few have heard about it! It is located about eight km away from Preveza and 83 km away from Sivota, in Epirus and it was built by the Roman emperor Octavian after his victory at Aktion against Antony and Cleopatra of Egypt! The size and its great walls are remarkable and stunning. Within the archaeological site, you will find many interesting monuments, which are to be admired. The archaeological site includes, a Conservatory, a Theater, two Early Christian basilicas with impressive mosaics, August’s memorial and a stadium. Also note that the Archaeological site of Nikopolis is included in the tentative list of UNESCO World Heritage Sites in Greece.
