Samrat Yantra

The Samrat Yantra is a massive stone sundial located in the Jantar Mantar observatories in India. Built in the 18th century by Maharaja Sawai Jai Singh II, it is one of the most precise astronomical instruments of its time.

The Samrat Yantra, which means "supreme instrument" in Sanskrit, is the largest sundial in the world, located in the Jantar Mantar observatories in Jaipur and Delhi, India. Built in the 18th century by Maharaja Sawai Jai Singh II, this monumental instrument stands about 27 meters tall.

The Samrat Yantra is designed to measure time with remarkable precision. It operates by using the shadow cast by the central gnomon onto a graduated scale on the sides. This accuracy was crucial for astronomy and astrology at the time. In addition to telling time, the Samrat Yantra can also determine the declination of the sun and other celestial bodies.

The structure is an engineering marvel, with staircases allowing astronomers to climb up for precise measurements. Today, it is recognized as a UNESCO World Heritage Site and continues to attract visitors from around the world, fascinated by its history and scientific significance.
