Jantar jaipur mantar

In the 18th century, Maharaja Sawai Jai Singh II, who ruled Jaipur, formed five observatories in northern India . These observatories are commonly referred to as Jantar Mantar. The other four are located in Mathura, Varanasi , Ujjain and Jaipur . Each building is unique in its structure, type of astronomical instruments and functions. The structure of the building resembles geometric shapes.

Sawai Jai Singh was a Mughal nobleman of court and this collection of observatories was built to satiate the Mughal emperor’s astronomical thirst. These instruments have been used in the past to record main phenomena. The data was collected functionally for seven years from the end of the Observatory. The data was drawn to the emperor. After the death of the last Mogul emperor, Aurangzeb, Muhammad Shah took the throne.

Jantar Mantar was built to find the correct position of the planets to determine the right moment during each day. Initially Jai Singh used brass instruments, which were not precise. Later, he adopted masonry instruments. After the fall of the Shah, the work of the Observatory was stopped.
