text_A: The ancient polis is to be distinguished from the municipality, which was named in its honor. The polis lay 17 ;km east-northeast of the mouth of the Nestos River, almost directly opposite the island of Thasos. It was a colony placed in previously unsettled Thracian territory, not then a part of Hellas, during the age of Greek colonization. The city that developed from it became of major importance in ancient Greece. After the 4th centuryAD it declined, contracted to its acropolis, and was abandoned, failing to be reoccupied except by archaeologists.
