 It was built to control the access route to Samlotha temple, which lies northeast of the fort, to collect the hefty jizya (religious ransom tax)from the Hindus pilgrimage.A hill divides the two lakes, the larger one is called Bhim Taal or just Tikkar Taal which is 550 meter wide and 460 meter long and the smaller one is called Draupdi Taal or Chota Tikkar Taal (meaning "the little tikkar lake") is 365 meter wide and long, as the legend goes there is a hidden channel linking them, as the water level of two lakes remains roughly the same.Morni locals look upon the lakes as sacred.
