“Jantar Mantar (Yantra - instruments, mantra - formulae) was constrcted in 1724. Maharaja Jai Singh of Jaipur who built this observatory went on to build other observatories in Ujjain , Varanasi and Mathura. Jai Singh had found the existing astronomical instruments too small to take correct measurements and so he built these larger and more accurate instruments.”
“The instruments at Jantar Mantar are fascinating for their ingenuity, but accurate observations can no longer be made from here because of the tall buildings around.”

What to see in Jantar mantar?
This unique observatory was completed in 1724 and remained operational only for seven years. Astronomical observations were regularly made here and these observations were used for drawing up a new set of tables, later compiled as Zij Muhammad Shahi dedicated to the reigning monarch. Jai Singh named his observatory Jantar Mantar (actually Yantra Mantra, yantra for instrument and mantra for formula). It is dominated by a huge sundial known as Samrat Yantra, meant to measure the time of the day accurate to within half a second and the declination of the sun and other heavenly bodies. Jai Singh himself designed this yantra. Other yantras were also meant for the study of heavenly bodies, plotting their course and predicting eclipses. The two pillars on the southwest of Mishra Yantra are meant to determine the shortest and longest days of the year. Interestingly, in December one pillar completely covers the other with its shadow while in June it does not cast any such shadow at all.
Spurred on by the completion of the first Jantar Mantar and with a view to verifying astronomical observations made at Delhi, Jai Singh built similar, if smaller observatories, at other important Indian cities-Jaipur, Varanasi, Ujjain, and Mathura. The state of these observatories is bad; the one in Mathura was demolished, while those in Ujjain and Varanasi are in state of decay. But the observatory at Jaipur is the best preserved of all because in 1901 Raja Ram Singh, the then ruler of Jaipur, refurbished it with the help of a British engineer. All the masonry instruments were lined with marble so that the graduations on them are not worn out.
The Jantar Mantars may have fallen into disuse but they remain an integral part of India’s scientific heritage. The Jantar Mantar in Delhi is often projected in travel books, brochures, on postage stamps and was the logo of the 1982 Asian Games. The Jantar Mantar shows that the spirit of scientific enquiry was not dead in India and would have yielded rich results if only an opportunity had been given to it to fructify. The Jantar Mantar on the Parliament Street remains one of the most intriguing structures of the capital, one that explodes in a burst of questions in the mind of the inquisitive tourist.
