Victoria Lautman's favorite pastime, or "obsession" as she calls it, is finding stepwells, large often cavernous wells in which water may be reached by descending a set of steps. Dating back as far as AD 600, these incredible architectural feats of design have been largely forgotten -- until now.
"In its heyday there were around 3,000 stepwells throughout India. Now, there are about 1,000 left," she estimates.
