History of Jantar Mantar Jaipur

Sawai Jai Singh II was a renowned scholar of his time. Once a while, Emperor Muhammad Shah assigned him a task to confirm and rectify the currently available data on the position and movement of celestial bodies.

Sawai Jai Singh was desperate to refine the tables of ancient Islamic zij to determine the exact time. In short, he aimed to create a well-defined calendar. He was keen on making accurate astrological predictions for the benefit of mankind.

 To bring his dream to reality, he decided that he would construct Jantar Mantar in the year 1718. For the same, he set out on a mission to extensively study the cosmological principles as laid down by the philosophical findings of Hindu, Islamic, European, and Persian civilization.

 In this way, five different astronomical observatories were constructed across various states in India.

The largest amongst all was built in Jaipur in between the period 1727 to 1733. After that, it underwent frequent renovations with the lapse of time.

The available instruments have a broad range of cosmological applications. In the year 2010, this astronomical observatory got featured in the list of UNESCO’s world heritage sites.
