Jantar Mantar is an astronomical observatory located in the heart of New Delhi, India. It was built by Maharaja Jai Singh II of Jaipur in the early 18th century, and it remains a fascinating example of the scientific and technological advancements of the time. The complex is home to several large instruments used for astronomical observations, including a massive sundial that remains accurate to this day.
The Jantar Mantar complex is located in the heart of New Delhi, near Connaught Place, one of the city’s major commercial centers. The observatory was built in 1724 by Maharaja Jai Singh II, a prominent astronomer and scholar who was also a skilled mathematician and astrologer. At the time, India was undergoing significant cultural and scientific changes, and Jantar Mantar was a testament to the country’s growing interest in astronomy and the natural sciences.

These instruments were used by Jai Singh and his fellow astronomers to study the heavens and make accurate predictions about astronomical events.
Today, Jantar Mantar remains an important landmark in the history of science and technology. The complex has been declared a national monument by the Indian government, and it is a popular destination for tourists and scholars alike.
