Hashtrūd
Hashtrud lies east of the Sahand massif in a country of hills and river valleys. The Qaranquchay drains the district toward the Qezel Uzan, gathering streams from the mountain slopes. Nearby stands the ancient fortress of Zahhak, set on a steep height above the river. Its surviving remains include structures from the Parthian period, a reminder of the long history of settlement and defence in these uplands.
