          Astarābādh (modern Gurgan), historically a province as well as a town, is located in what the ancient Greeks called Hyrcania, adjacent to the Persian province of Māzandarān. The city, some thirty kilometres east of the Caspian Sea, has origins going back to Achaemenid times (550–330 B.C.E.).
