Copae or Kopai (Greek, Ancient (to 1453);: Κῶπαι), or Copia or Copiae, was an ancient Greek city (polis) in Boeotia, on the northern shore of Lake Copais, which derived its name from this town.[1] Copae was part of Thersander's kingdom and is mentioned by Homer in the Catalogue of Ships in the Iliad. It was a member of the Boeotian League. It was still in existence in the time of Pausanias, who mentions here the temples of Demeter, Dionysus and Sarapis.[1]
Its site is located near the village of Kastro, formerly Topolia.
