JantarMantar
Jantar Mantar located in New Delhi is built by Maharaja Jai Singh II of Jaipur in the year 1724. The maharaja built five observatories during his ruling time in the 18th century. Among these five the one in Delhi is the first to be built. The other four observatories are located in Ujjain, Mathura, Varanasi, and Jaipur.
The objective 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 one of its kind at the time it was built. By the year 1867, when India came under the control of foreign invaders the observatory underwent considerable decay. later after many years the Government of India came forward and took several initiatives to restore and maintain the historical observatory and promote it for tourism in Delhi.
