Visitors can explore the site, learn about ancient astronomical techniques, and even witness demonstrations of how the instruments were used. It's a unique blend of history, science, and architecture, offering a captivating glimpse into India's rich scientific heritage.
Jantar Mantar was built in 1724 by Maharaja Jai Singh II, a Rajput king with a keen interest in astronomy. He constructed five observatories across India, including the one in Delhi, as part of his effort to improve astronomical calculations and create accurate calendars. The Delhi Jantar Mantar, considered the most significant of the five, reflects the astronomical traditions prevalent during the Mughal era, combined with influences from Islamic, Hindu, and European astronomical schools of thought. Over the centuries, the observatory has undergone some restoration and conservation work to preserve its historical and scientific significance.
