The Jantar Mantar was the largest of the five Astronomical Observatories built by Jai Singh. The Samrat Yantra is the world's largest sundial, standing 27 meters (73 feet) high.The Samrat Yantra, pictured far right and in illustrations, below, is the largest sundial in the world. It’s gnomon rises over 73 feet above its base, and the marble faced quadrants, 9 feet in width, create an arc that reaches 45 feet in height.The primary object of a Samrat is to indicate the apparent solar time or local time of a place. On a clear day, as the sun journeys from east to west, the shadow of the Samrat gnomon sweeps the quadrant scales below from one end to the other. At a given moment, the time is indicated by the shadow’s edge on a quadrant(soirce:www.jantarmantar.org/Architecture_Science_web.pdf)

  • The Jantar Mantar was an Astronomical Observatory and not an astrological one. This marker locates the great Samrat Yantra at the Jaipur Jantar Mantar.
  • This Yantra (SUN DIAL)is capable of indicating Local time & hence Indian Standard Time with an accuracy of 2 seconds !!!. Isn't it fascinating? This Sun Dial is recorded in Guiness Book Of World Records.
