Prison of Solomon

The Prison of Solomon is a hollow cone shaped hill in West Azerbaijan province, Iran [1]. There is an 80 meters deep pit in the middle of the hill, and the entrance to the pit is roughly 65 meters in diameter [1]. The hill is the result of an Artesian spring first creating a small pond [1]. Lime and other minerals then slowly sedimented around the pond and created a wall [1]. The spring then dried, leaving a hollow hill behind [1]. Located 3 kilometers west of Takht-e Soleymān, the place has been subject to many religious and cultural practices through ages [1]. It used to be surrounded by walls and hosted a Mannaean temple in 880–660 BCE [1].
