Abydos (Ancient Greek: Ἄβῡδος) or Abydus, an ancient city of Troad (Troas), in Asia Minor, situated at Nara Burnu or Nagara Point on the best harbor on the Asiatic shore of the Hellespont. Across Abydos lies Sestus on the European side, marking one of the narrowest points of the Dardanelles, slightly more than a nautical mile broad (the narrowest point is at Çanakkale). The strategic site has been a prohibited zone in the 20th century.
