Zendan -e- Soleyman (Salmon's Prison)is the name of a volcanic conical void core mount, located 3km away from Takht -e- Soleyman. It is a 97 to 107m tall mount with a huge hole on top, with 65m span and around 80m depth. The hole was full of water, fed by floor springs and after an earth quake begins to dry, centuries ago. Remnants of a pre-historic and a Median temple are explored in the region.
