Durun

Durun belongs to the oasis country along the northern foot of the Kopet Dag, where settlements and cultivated land depend on water descending from the mountains. This belt lies between the highlands and the Karakum Desert and connects neighbouring districts of western Khorasan.

Persian reference works describe a town called Darun in Khorasan in relation to Merv and Nisa. The nearby Nisa district was known for its cultivated lands and its position on routes through the region.
