By 1728, many of the instruments in the Jaipur site were built and the construction continued till 1738. About 23 astronomers were employed to build the instruments in Jaipur and in 1735, with the shifting political climate in the country, Jai Singh replaced the Delhi site as the main observatory, which remained until his death in 1743.

The support and authority of the observatory changed many hands with his successors when the developments of this place died down. Under the rile of Pratap Singh (1778 – 1803) the observatory was turned into a gun factory. 

The monument got damaged in the 19th century. Major Arthur Garrett, an amateur astronomer who was appointed as an assistant state engineer in Jaipur, took on the early restoration work. The then king of Jaipur, Ram Singh Jr. completed the restoration in 1876 and reinforced some of the instruments as well. During the colonial era, the Jantar Mantar went through further restorations and even after that in the 2000s
