Takht-e Soleymān (Persian: تخت سلیمان), also known as Azar Goshnasp Fire Temple (Persian: آتشکده آذرگشنسپ), is an archaeological site in West Azarbaijan, Iran. It lies midway between Urmia and Hamadan, very near the present-day town of Takab.
The fortified site, which is located on a hill created by the outflow of a calcium-rich spring pond, was recognized as a World Heritage Site in July 2003. The citadel includes the remains of a Zoroastrian fire temple built during the Sassanid period and partially rebuilt (as a mosque) during the Ilkhanid period. This temple housed one of the three “Great Fires” or “Royal Fires” that Sassanid rulers humbled themselves before in order to ascend the throne. The fire at Takht-i Soleiman was called ādur Wishnāsp and was dedicated to the arteshtar or warrior class of the Sasanid. A 4th centuryArmenian manuscript relating to Jesus and Zarathustra, and various historians of the Islamic period, mention this pond. The foundations of the fire temple around the pond is attributed to that legend. Takht-E Soleyman appears on the 4th century Peutinger Map.
This site got its biblical name after the Arab conquest. Folk legend relates that King Solomon used to imprison monsters inside a nearby 100 m deep crater which is called Zendan-e Soleyman “Prison of Solomon”. Solomon is also said to have created the flowing pond in the fortress.
Archaeological excavations have revealed traces of a 5th-century BC occupation during the Achaemenid period, as well as later Parthian settlements in the citadel. Coins belonging to the reign of Sassanid kings, and that of the Byzantine emperor Theodosius II (AD 408-450), have also been discovered there.
Criteria that make this place unique and part of world heritage are as follows:
Criterion (i):Takht-e Soleyman is an outstanding ensemble of royal architecture, joining the principal architectural elements created by the Sasanians in a harmonious composition inspired by their natural context.
Criterion (ii):The composition and the architectural elements created by the Sasanians at Takht-e Soleyman have had strong influence not only in the development of religious architecture in the Islamic period, but also in other cultures.
Criterion (iii):The ensemble of Takht-e Soleyman is an exceptional testimony of the continuation of cult related to fire and water over a period of some two and half millennia. The archaeological heritage of the site is further enriched by the Sasanian town, which is still to be excavated.
Criterion (iv):Takht-e Soleyman represents an outstanding example of Zoroastrian sanctuary, integrated with Sasanian palatial architecture within a composition, which can be seen as a prototype.
Criterion (vi): As the principal Zoroastrian sanctuary, Takht-e Soleyman is the foremost site associated with one of the early monotheistic religions of the world. The site has many important symbolic relationships, being also a testimony of the association of the ancient beliefs, much earlier than the Zoroastrianism, as well as in its association with significant biblical figures and legends.
