Jantar Mantar in New Delhi is an observatory, designed to be used with the naked eye. It is one of five Jantar Mantar in India. "Jantar Mantar" means "instruments for measuring the harmony of the heavens". It consists of 13 architectural astronomy instruments. It is one of five built by Maharaja Jai Singh II of Jaipur, from 11723 onwards, revising the calendar and astronomical tables.
Jai Singh, born in 1688 into a royal Rajput family that ruled the regional kingdom, was born into an era of education that maintained more interest in astronomy. There is a plaque fixed on one of the structures in the Jantar Mantar observatory in New Delhi that was placed there in 1910 mistakenly dating the construction of the complex to the year 1710.
Jantar Mantar is located in New Delhi which was built by Maharaja Jai Singh II of Jaipur in 1724. The Maharaja built five observatories during his rule in the 18th century. Among these five, the one in Delhi was the first to be built.
The purpose behind the construction of these observatories was to assemble astronomical data and to accurately predict the movement of the planets, Moon, Sun etc in the Solar System. It was a one of a kind in its time when it was built. By the year 1867, when India was under the British Raj, the observatory had undergone severe damage.
Delhi bus stand is located at a distance of around 6 KM from the Jantar Mantar and can be reached by taking a local bus or taxi from the bus stand.
