Takht-e Soleyman
Throne of Solomon: a Sassanid fire-temple ringed around a bottomless crater lake
8 highlights · tap a pinTakht-e Soleyman ("Throne of Solomon") is a fortified Sassanid sanctuary in a remote volcanic valley of West Azerbaijan, built around an artesian crater lake whose calcium-rich waters raised the whole platform some 60 m above the plain. It was the holiest site of state Zoroastrianism, home to Adur Gushnasp (Azar Goshnasp), one of the three Great Royal Fires reserved for warriors and kings, and was later rebuilt as an Ilkhanid (Mongol) summer palace in the 13th century. The site's fire temple, water shrine to the goddess Anahita, and oval fortifications strongly influenced later Islamic architecture, earning UNESCO World Heritage inscription in 2003. Its layered legends — Solomon's throne, a prison of monsters, the cradle of the True Cross relic under Khosrow II — make it one of Iran's most atmospheric archaeological landscapes.

The Crater Lake (artesian spring lake)
Mineral-blue artesian lake at the heart of the sanctuary, roughly 80 m across and over 60 m deep. The reason the whole site exists: a calcium-saturated spring that built its own raised travertine platform over millennia, lifting the temples ~60 m above the valley. Sacred to Anahita; pilgrims cast offerings into its depths. Holds a constant 21C year-round.
