With a geo­met­ric pat­tern of 3,500 nar­row steps, 13 storeys, and 30 meters of depth, the step­well in Chand Baori is the world’s largest step well. Built in the 9th or 10th Cen­tu­ry by the Kind Chan­da, it is a source of water, med­i­ta­tion, prayer, and bathing. On three sides, stairs enclose the water, while the fourth side has a three storey pavil­ion.
