Two different legends claim to explain the name of the well. One says that the king ordered a stepwell to be built and workers excavated down into this hard stone but no water was found.
The royal priest said that water would only be found if two unmarried girls were sacrificed. Adi and Kadi were the unlucky ones chosen for this and after their sacrifice, water was found.
The other story, less fantastic but probably more likely claims that Adi and Kadi were the names of the royal servant girls who fetched water from the well every day, either way people still hang cloth and bangles on a tree nearby in their memory.
