It is supposed that the wells of a depth of 30 m, the stairs of 13 layers, and 3500 steps of huge stairs were built in the 10th century.
Even if it is seen with a photograph, precise structure which seems to have used the machine is known.
It has been handed down that the ghost built it in a night.
A great many stepwells in India.
