Jantar Mantar Jaipur and its history

In the early 18th century, Emperor Muhammad Shah commissioned Maharaja Sawai Jai Singh II, the ruler of Amer and Jaipur to make corrections in the astronomical tables on the planetary positions and to confirm the data. 

Being a genius in astronomy, Maharaja Sawai Jai Singh II thought of doing more than the allocated task. Now, those were the days when no astronomical observatories were found in India. So, he planned to construct five Jantar Mantar. Keeping his reign and ties in mind he initiated the construction work in five cities – New Delhi, Ujjain, Mathura, Varanasi, and Jaipur. Unfortunately, Jantar Mantar Mathura got lost in the tide of time. However, the other ones still stand relevant in this 21st century.

Jotshi Gokul Chand Bhawan restored this sundial in A.D. 1901 for finding time and declination and hour angle of different heavenly bodies and today this world’s largest sundial stands tall. Its gnomon arm is 22.6-meter high and its largest quadrants are of the 15.5-meter radius.
