Jantar Mantar, New Delhi (India)
Jantar Mantar is located in the modern city of New Delhi. “Jantar Mantar” literally means “instruments for measuring the harmony of the heavens”. It consists of 13 architectural astronomy instruments. The site is one of five built by Maharaja Jai Singh II of Jaipur, from 1723 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 a keen 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. Later research, though, suggests 1724 as the actual year of construction. Its height is 723 feet (220 m).
The primary purpose of the observatory was to compile astronomical tables, and to predict the times and movements of the sun, moon and planets. Some of these purposes nowadays would be classified as astronomy.
Completed in 1724, the Delhi Jantar Mantar had decayed considerably by 1857 uprising. The Ram Yantra, the Samrat Yantra, the Jai Prakash Yantra and the Misra Yantra are the distinct instruments of Jantar Mantar. The most famous of these structure, the Jaipur, had also deteriorated by the end of the nineteenth century until in 1901 Maharaja Ram Singh set out to restore the instrument. The most important issue concerning the Jantar Mantar is the loss of the fine, calibrated markings on the instruments, which are eroding. These precision machines needed to be completely restored in order to protect the historic function of these extraordinary instruments. In 2008, advocacy groups formed in an effort to encourage the Rajasthan government to restore the Jantar Mantar. The restoration proceeded and is now what we see today. In 2010, the Jantar Mantar was inscribed on the UNESCO World Heritage List. The constant modification and corrections in the observed and mathematical tables of astronomy made these positional astronomical instruments play a key role in the continued study and development of astronomy across the globe.
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.
Between 1727 and 1734 Jai Singh II built five similar observatories in west-central India, all known by the name Jantar Mantar. They are located at
While the purpose of the Jantar Mantar was astronomy and astrology (Jyotish), they are also a major tourist attraction and a significant monument of the history of astronomy.
