Jantar Mantar - Delhi’s Ancient Astronomical Observatory,

Jantar Mantar in Delhi is a historic observatory built in 1724 by Maharaja Jai Singh II of Jaipur. It was designed to study the movements of the sun, moon, and planets with the help of giant astronomical instruments, long before modern technology was invented.

The site has 13 huge instruments made of stone and marble, each with a special purpose. The most famous one is the Samrat Yantra, a giant sundial that can measure time with surprising accuracy. Other instruments were used to track stars, predict eclipses, and study the position of celestial bodies.

Walking through Jantar Mantar feels like stepping into a blend of science and art. The structures are beautifully designed, and their massive shapes stand out against the backdrop of modern Delhi. It’s not just a place for historians or scientists - travelers, students, and photographers love visiting here too. Located on Sansad Marg in Connaught Place, Jantar Mantar is easy to reach and open daily from 6:00 AM to 6:00 PM. 

Jantar Mantar is more than just an old observatory - it’s a reminder of India’s scientific knowledge, architectural skill, and curiosity about the universe. If you’re in Delhi, this UNESCO World Heritage Site is a must-see.
