If you like science, especially astronomy, this place will utterly astound you. There are numerous astronomical instruments built in very large scale for accuracy. The sun dial alone is several stories tall and is accurate to within 30 seconds. How did they figure this out 300 years ago?

it is also another showcase of ancient Indian knowledge. the 'rajpoot rajas', who were lord of delhi & suburban areas before any middle eastern invaders took the throne of India over, built this place for astronomical research & forecasting. the machines and arrangements situated here are the most bigger brothers of the miniatures we use these days. :)

Built by Sawai Jai Singh in 1728, to get an accurate clock, he had several attempts, His most accurate one was accurate to two seconds, unfortunately to large to wear on the wrist. Visit this place and see why

let me make it clear, however good you are in trigonometry you will not be able to understand how the whole find-the-time-using-sun works. its a good,yet a old and fading attraction which in need of restoration. the complex itself is small with odd shaped structures in it. not much to see for a traveler other than rest in the grass...

I had been to this place earlier too....This time with my kid. He was amazed to see the sun clock and how it helps to calculate time. There are many such scientific instruments which are great learning for kids. One must have a guide to get to know this place well. My kid loved this place

Good for family outing where the kids can learn as well as play. I had a gala time with my family. The only problem here is the sunlight which I had... More

There are two well known observatories in India and this one is in New Delhi. It is very interesting to visit but is not particularly well maintained. Still worth a visit.
