Asopus or Asopos (Greek, Ancient (to 1453);: Ἀσωπός), also known as Asopolis (Ἀσώπολις), was a town of ancient Laconia, on the eastern side of the Laconian Gulf, 60 stadia south of Acriae. It possessed a temple of the Roman emperors, and on the citadel a temple of Athena Cyparissia. At the distance of 12 stadia above the town there was a temple of Asclepius.[1] Pausanias says that at the foot of the acropolis of Asopus were the ruins of the city of the Achaei Paracyparissii. Asopus was a town of the Eleuthero-Laconians.
Its site is located near the modern Plytra.
