Samrat Yantra

The Samrat Yantra is a large, ancient Indian astronomical instrument located in Jaipur's Jantar Mantar observatory. It functions as a giant sundial, designed to measure the precise time of day, track the Sun's position, and determine local noon. Its massive structure, with a shadow-casting gnomon and marked scales, allows astronomers to observe celestial events accurately. The Samrat Yantra exemplifies India's rich tradition of astronomical observation and engineering, combining scientific purpose with impressive architectural design. It remains a significant historical instrument that reflects the advanced understanding of astronomy prevalent in 18th-century India.
