The Adi-kadi Vav & Navghan Kuwo are the two famous stepwells located within the Uparkot Fort. While the former was built by two slave girls of the Chudasama kingdom, the latter came into being much before the Adi-kadi Vav.
The Adi-kadi Vav is a 9-layered step well from the 1400s. However, this stepwell is also attached to a tragic story. While the girls were at the task, they were unable to dig out any water. Thus, the local priest pronounced that water would surface only if Adi and Kadi, the two unmarried girls were sacrificed. Thus, this piece of history also has a tragic story.
However, the Navghan Kuwo is a relatively early well that was constructed sometime during the 1060s. One significant feature of this stepwell is its underground spiral stairway that meets the bottom where the water is found. Carved in soft stone, the Navghan Kuwo is a unique stepwell.
