Standing proudly in the heart of New Delhi, Jantar Mantar is not just an ancient observatory but a testament to India’s scientific brilliance. Built in 1724 by Maharaja Sawai Jai Singh II of Jaipur, this UNESCO World Heritage Site is one of the five astronomical observatories he constructed across India. Unlike modern telescopes, Jantar Mantar’s massive masonry instruments were designed to track celestial movements with astonishing precision.

The History of Jantar Mantar: Where Science Meets Art
The Vision of Maharaja Sawai Jai Singh II
Jantar Mantar was built by Maharaja Sawai Jai Singh II, a Rajput king with a deep passion for astronomy. Dissatisfied with the inaccuracies of existing astronomical instruments, he designed these colossal structures to observe planetary positions, predict eclipses, and measure time with unmatched precision.
The Five Jantar Mantars
Jai Singh built five observatories across India:
- Delhi (1724) – The first and most prominent
- Jaipur (1734) – The largest and most well-preserved
- Ujjain (1733)
- Varanasi (1737)
- Mathura (1734) (now mostly destroyed)
The Delhi Jantar Mantar, though smaller than Jaipur’s, remains a masterpiece of ancient Indian astronomy and architecture.
Key Instruments at Jantar Mantar
- Samrat Yantra (The Supreme Instrument) – A giant sundial that measures time accurately to within 2 seconds.
- Jai Prakash Yantra – Used to determine the position of the sun and other celestial bodies.
- Misra Yantra – A composite instrument that could calculate the shortest and longest days of the year.
