Jantar Mantar, New Delhi

Jantar Mantar, one of five open-air astronomy sites built by Maharaja Jai Singh II, contains instruments once used to revise the calendar and astronomical tables. Built in the 18th century, the facility allowed scientists to observe movements of the sun, moon, and planets. During your visit, look for individual instruments like Samrat Yantra, a huge triangle used as an equal hour sundial, as well as Misra Yantra, which measures the longest and shortest days of the year. Detailed descriptions in English accompany each instrument, so you may not need to hire a guide.

  • I've been to the Jantar Mantars in both Delhi and Jaipur and I like the Delhi one the best. I think it's the deep red colour of the buildings that appeals, plus the general crazy 'feel' of the place. ...  more »
  • Nice Place to visit. Location and open spaces make it for good family outing. As a tourist, don't expect to spend too much time but good for photo opportunities. If you have an interest in Astronomy, then it is a good place to visit. Shows how people in that time knew so much about Space and Solar system.
  • It is a very good place to visit. It is a historical place with a lot of old scientific buildings used to calculate the time and tell what date it is. It was also used for finding distances of astronomical objects in space. It also has two pillars which can tell when it is summer solstice and winter solstice. Currently the building is not working because of the skyscrapers built near it which blocks the sunlight and the whole thing is based on sun and its light. By the way there are guides available there in a very reasonable cost to explain the working of this place
  • Neat place to hang out and learn a little bit about how astrology worked few hundred years ago. Parts were under construction when I visited, but the park was still open and accessible. They don't let you get too close to some of the tools, but it is very picturesque and totally worth the time, even if you do not spend too much of it there. If you are in Delhi, and have time to kill, put this on your list.
  • Astronomical laboratory for measuring the position of celestial objects over time, particularly the sun and planets. Instruments are less well preserved/maintained than the similar site in Jaipur, but still very impressive. Worth a visit for anyone interested in historical astronomy.
  • a good place to indulge into rich heritage of Science and astronomy with your family and friends. the design of structures make you awestruck about the knowledge of people in the past and the accuracy of calculations. p.s. however, people treat the structures as a piece of brick and .mortar rather than scientific equipments. it's a gentle request to all who visit this place to see and treat as a piece of science rather than photo stand, refrain from jumping or climbing on the structures as it can damage the fine markings on it.
