Bai Harir Sultani, the Royal Harem's supervisor, and Mahmud Begada's housekeeper commissioned the construction of this vav. Dada Hari ni Vav's grave is located in the Sultani Mosque directly below hers. Almost 3,29,000 Mahmudis had been spent on the construction of this vav at the time (money used during those days). In today's money, that's more than a lakh rupees.The seven stories of Dada Hari ni Vav are all equally stunning. The stepwell is particularly impressive in daylight when the detailed carvings on the walls, columns, and pillars can be appreciated. There is a mix of Muslim and Hindu architectural styles in this vav. Floral designs and traditional sculptures adorn the walls, as do Arabic and Sanskrit literature.Photographs are frequently taken by visitors while perched on the railing above the vav. The stairwell's octagonal shape is stunning when viewed from the top floor. Going down the steps and looking up at the vav from the middle is just as exciting. It appears to be a toran or stone pendant hanging from the railings of each story below the railings.
