 Seven years later, Jahangir's son Shah Jahan, who was no less a lover of natural beauty, constructed cascades and aqueducts in straight lines through and around the fine garden which he, in order to enhance further the beauty of the place laid out in front of the spring.He also built hot and cold baths to the east of this garden, just outside it, of which little trace is now left.The water contained in an octagonal spring has crystal blue water in which a variety of big fishes live.
