Stepwells, also known as kalyani, pushkarani, bawdi, baoli, barav, or vaav; are wells or ponds in which the water may be reached by descending a set of steps. They may be covered and protected and are often of architectural significance. Most common in Western India, they can also be found in arid regions of Pakistan.
The basic difference between stepwells and tanks or wells is that stepwells are easier for people to reach the ground water. They are also easier to maintain and manage. Stepwells also served other purposes, such a relief from the daytime heat and as a place for social gatherings and religious ceremonies.
