Maharaja Sawai Jai Singh II erected a cluster of fixed stones and very big constructions in the early 18th century. Each has a specific application. It was built primarily due to the Maharaja's fascination with celestial objects and the movement of various bodies in the sky.

The history of Jantar Mantar Jaipur is that it contains 19 large instruments, each with a specific purpose, the most popular and visible of which is the Samrat Yantra. It is regarded as the country's largest sundial.  The magnificent monument's construction was completed in 1734. The main feature of the instruments is the ability to observe celestial objects with the naked eye. It is based on Ptolemaic positional astronomy, which has parallels throughout history with numerous civilizations.
 

When talking about Jantar Mantar Jaipur Architecture, the king is said to have used the knowledge and skill of 23 Jaipur astronomers to make his dream a reality. The observatory has overcome many challenges over the years and has emerged as a national architectural masterpiece.

The monument itself is made of locally sourced marble and stone. Each instrument in this observatory was meticulously planned and has an astronomical scale. This huge structure is 18000 square meters in size. The most prominent materials used to construct the structure were tablets, bronze tablets, and mortar, which made it strong and sturdy even today.
