One of the famous Jantar Mantar observatories of India, Jantar Mantar in Delhi is a vast observatory built to help and improve the studies of time and space. It was built by Maharaja Jai Singh in the year 1724 and forms a part of five such observatories in Jaipur, Ujjain, Varanasi, and Mathura. Delhi’s Jantar Mantar consists of 13 architectural astronomy instruments which can be used to predict the movement and timings of the sun, moon, and planet. The beautiful construction and placement of these instruments allowed the observer to note the position of heavenly bodies with their naked eyes.
Maharaja Jai Singh II of Jaipur was keenly interested in these astronomical observations and the study of all systems. It was built out of brick, rubble, and then plastered with lime, these instruments have been restored from time to time without making any significant revision. The apparatus here pertains to Egypt’s Ptolemaic astronomy and follows three classical celestial coordinates to track the position of heavenly bodies. The Samrat Yantra, the Jai Prakash, Ram Yantra, and Misra Yantra are some of the most amazing attractions of this Jantar Mantar observatory.
