Parium

Parium (or Parion; Greek: Πάριον) was a Greek city of Adrasteia in Mysia on the Hellespont. Its bishopric was a suffragan of Cyzicus, the metropolitan see of the Roman province of Hellespontus.

Founded in 709 B.C., the ancient city of Parion is located in the village of Kemer in the township of Biga in Çanakkale province of Turkey, currently. A major coastal city with two harbors in the Roman period, Parion had intensive relations with Thrace and Anatolia throughout history. This was the main customs station through which all Istanbul-bound goods from Greece and the Aegean had to pass.

On the history: Located near Lampsacus, it was a colony probably founded by Eretria and Paros. It belonged to the Delian League. In the Hellenistic period it came under the domain of Lysimachus, and subsequently the Attalid dynasty. In Roman times, it was a colonia, within the province of Asia; after that province was divided in the 4th century, it was in the province of Hellespontus. The ancient coinage of Parium is quite abundant, attesting to its great output and advanced mint (in Hellenistic times, the city's badge shown on coins was the Gorgoneion).
