Jantar Mantar, literally "calculation instrument," is a series of masonry devices intended to be used with the naked eye to accomplish various astronomical measurements and predict the movement of celestial bodies. There are five Jantar Mantar sites in India, all built in the early 18th century by Maharajah Jai Singh II, who had a lifelong interest in astronomy. Those in Jaipur and Delhi are the largest and most well known, but there are also sites in Varanesi, Ujjain and Mathura. The Jantar Mantar in Jaipur contains over twenty instruments, including the largest sundial in the world.
