Temple of Hercules

Cleonae or Kleonai was a city in ancient Peloponnesus, described by writers of the Roman period as a city of Argolis, but never included in the Argeia or territory of Argos, in the flourishing period of Greek history. Cleonae was situated on the road from Argos to Corinth, at the distance of 120 stadia from the former city, and 80 stadia from the latter. There was a narrow pass through the mountains, called Tretus, leading from Argos to Cleonae.
