Temple and mosques were erected inside with lots of sculptures to make the whole construction an embodiment of archeological beauty.

She was a popular figure during the Mahmud Shah’s reign and with her requisition this step well was established. However, she was better known as Dhai Harir and her burial tomb is the cater piece in this step well. In course of time the name of this historical structure modified and became Dada Hari Ni Vav. This is one of the greatest tourist pullers of Gujarat Tourism.
