Known in Islamic times as Takht-e-Soleyman, this Sasanian site is situated in province of East Azerbaijan, five km north of the city of Takab. It is believed that fire of Adur Gushansp was first installed here sometime before AD 400. Later Sasanian kings had a tradition of traveling there on foot before their coronation out of respect for the fire in this temple. There was an enormous wall made of mud bricks which encircled the temple to ensure its safety. In later Sasanian times a stone wall of 50 feet high and 10 feet thick was built. The temple had many rooms including a treasury which included many priceless objects. No objects from before the time of Pērōz (A.D. 457-84) has been found. The temple was sacked by the Byzantine emperor Heraclius in AD 623 in his counter offensive against Khusro II Aparviz. The fire was supposedly carried away to safety and was later reinstalled.
