Kameiros is an ancient city and a former municipality on the island of Rhodes, in the Dodecanese, Greece. Since the 2011 local government reform it is part of the municipality Rhodes, of which it is a municipal unit. It lies on the northwest coast of the island. It was the heart of an agricultural region, and constituted one of three city states on Rhodes.
The ancient city was built on three levels. At the top of the hill was the Acropolis, with the temple complex of Athena Kameiras and the Stoa. A covered reservoir having a capacity of 600 cubic meters of water—enough for up to 400 families—was constructed about the sixth century BC. Later, the Stoa was built over the reservoir. The Stoa consisted of two rows of Doric columns with rooms for shops or lodgings in the rear.
