Копетдаг
There is archaeological evidence of settlement in the well-watered northern foothills of the Kopet Dag during the Neolithic period. This region is dotted with the multi-period hallmarks characteristic of the ancient Near East, similar to those southwest of the Kopet Dag in the Gorgan Plain in Iran. At Jeitun (or Djeitun), mud brick houses were first occupied c. 6000 BC (see BMAC origins). Also the foothills of the Kopet-Dag near Ashgabat are the site of the remains of the ancient Parthian city of Nisa (Nessa, Nusaý).
