Jantar Mantar is located in the heart of Delhi, right in the middle of Connaught Place. It was built in 1724 by Maharaja Jai Singh II and stands as a testament to ancient India’s scientific advancements.
During the reign of Muhammad Shah, a debate arose between Hindu and Muslim astronomers regarding the position of celestial bodies. To resolve this dispute, Jai Singh II commissioned the construction of Jantar Mantar. Similar observatories were also built by him in Jaipur, Ujjain, Mathura, and Varanasi.
The Jantar Mantar in Jaipur was declared a UNESCO World Heritage Site in 2010. The observatory was designed for the study of time and space, and it houses the world’s largest stone sundial, known as the Vrihat Samrat Yantra, which accurately measures local time. Additionally, various instruments are installed here to track the motion of planets.
