According to the folks who lived around, the king use to bathe in this pond so often when he is in the palace .The ancient irrigation engineers who designed this had tried to get the advantage of its natural existence of this part of the rock.This is further supported by converting a cavity on the rock to a pond. It is still a mystery the way the water being pumped up to ponds as there are no fountains found on top of the rock. The rumor says that water is carried to the ponds from the summit of a mountain which is in a higher elevation than the Sigiriya rock. The elevation difference creates the required head to pump the water. However, still it’s a mystery.
