Jantar Mantar, situated at Jaipur, is the largest stone observatory in the globe. Jantar Mantar is one of the five astronomical observatories constructed by the founder of Jaipur- Maharaja Jai Singh. The name 'Jantar Mantar' is taken from the Yantra Manta, a Sanskrit word that refers to instruments and formulae. The 'Yantra Mantra' factually denotes 'Magical Device'.

An Overview Maharaja Jai Singh was a reputed astronomer. Emperor Muhammad Shah commissioned him to rectify the astronomical tables and to validate the data available on the positions of the planets. Jai Singh then built Jantar Mantar in seven years. This edifice was restored in the year 1901 and was declared as a national monument in the year 1948.
