Jantar Mantar, New Delhi

3.6
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 visited on a Friday morning. There were very few people. The staff were very approachable. There as a Hindi speaking guide inside the campus. The descriptions given by archeological survey of India aren't sufficient for us to understand the nature of the observatory of that bygone era. The campus was maintained well and was very clean. Would love to visit again. Entry fee was Rs 15/- per head
  • Nice place to spend some time. There are sun dials which were used to calculate time depending upon the shadow created by the Sun. The place is pretty well maintained and easily accessible via the metro as well as road. The reason for 3 stars is that, this place is particularly surrounded by the protesters from all across the country for various reasons, as the Ministry of Home Affairs, Government of India office is just opposite it.
  • It is amazing to see all those instruments that were used to measure time and position. Sadly very little guidance is there to see how exactly they work. There are few guides moving around, claiming to tell about the instruments for a fee of Rs.50, but they add no additional value than what is found in google. If they had included a film on how these instruments actually work, it would be more fascinating. There is a restriction of entry into the instruments and so you have to see them only from outside. The archeological society seems to be doing very little to make this place more attractive. I may be wrong but there was very little evidence to prove otherwise. The entry fee is nominal but the parking could be an issue if you come by afternoon time
  • A good historical place. It is not much big. Half an hour is enough for the visit. I would recommend not to take children at this place. They would never be going to have fun there.
  • Truly a piece of historical amazement. You get to an entire campus full of astronomical gadgets. Incidentally all these state of the art gadgets of erstwhile era provided information which is readily accessible in the black mirror we carry in our pockets. 1 star less because the place has been vandalized by lovers who believe inscribing their names would help the world know about them.
