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 »
  • 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
  • An architectural marvel showcasing the intelligence of our ancestors. The Yantra's at Jantar Mantar were used to study the celestial bodies. The place is its current form is really beautiful and soothing to just sit and relax. Covered around with a lot of greenery makes it an ideal spot to go out with kids and family. As I'm writing this review most of the architectures were under maintenance.
  • 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.
  • It is a fun place for family . "These observation facilities show the wisdom of ancient Indian people." ""Beautiful place except foul smell in Some of the rooms..."" cafe and likely the one that's opens the earliest on the street. The place to go for coffee in the morning if you want to spend some time on th... Really nice people and very community oriented. This is the place to go for all formal wear prom, weddings, etc
  • The architectural brilliance of the contemporary kings can be observed here in the midst of modern day New Delhi. The astronomical instruments featured here were being restored at the time of writing this review. Strange was the scenario to me when I was there, as I found most people there were uninterested in their own historical wonders. Not much of a crowd can be found, and therefore, the place has conveniently become a safe haven for young lovebirds.

Where to stay in New Delhi

New Delhi contains some of India's finest and most popular hotels, catering to business travelers and well-heeled tourists. For budget accommodations, consider the neighborhood of Paharganj, just west of the New Delhi railway station. Noisy and packed with peddlers of every kind, the area offers some of the least expensive rooms located relatively near major attractions. Guesthouses serve as the city's best mid-range option, with new ones constantly springing up to satisfy the growing number of visitors. Always call or visit the website in advance to check on prices and amenities included.
