Jantar Mantar - a marvellous astronomical observatory
The Jantar Mantar in Jaipur is a collection of nineteen such instruments. The capital city of Rajasthan was the seat of Maharaja Jai Singh II who oversaw the completion of this monument in the year 1734. A renowned scholar and a passionate astrologer, the Maharaja studied philosophy, astrology, architecture, and religion and was also well versed with universal mathematical concepts as well. The Jaipur observatory was functional for seven years only, as the Maharaja was not very successful in deriving accurate, astronomical observations.
