Takht-e Soleyman
A Sassanid fire temple complex built around a deep spring-fed lake in a volcanic crater rim.
Updated 31 August 2026
UNESCO World Heritage
Takht-e Soleyman sits at about 2,200 metres on a natural mound built up by mineral deposits from a spring, with a lake around a hundred metres deep in the middle of it, and around that lake the Sassanids built one of the three great fire temples of the empire, Adur Gushnasp, associated with kings and warriors, where rulers came on foot after coronation. The complex has an oval enclosure wall with thirty-eight towers, the temple, halls and a later Ilkhanid palace built into the same site in the thirteenth century. The lake drains through channels and the deposits it lays down have raised the whole mound over millennia. Nearby stands Zendan-e Soleyman, a hollow cone of the same mineral origin with a deep shaft inside.
