A must visit place in Delhi. Be sure to visit it before 4,as after that the sun clock would not make much sense. Built in the 18th century this place is an exemplary show of brilliance. A very small place by the look of it, it has some astonishing instruments. Things to look out for Sun clock International clock Solar and lunar calenders Details of solstice and equinox Take a guide if you want to know details of the instruments, its worth the money.

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.

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.

Paras Gangh | Mar 23, 2018

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.

I think this is a much better experience if you have a friend or guide with you to explain the context of what you're looking at. It's a fantastic example of ancient engineering but lost on me without a scientific ' translator'. Once you pay your money at the entrance you're left to your own devices. It was an early morning visit so l got the benefit of good light to take pictures. My loneliness was dispelled for me by the cute local squirrel who did various acrobatics across the trees.

Um well I didn't find this place interesting, except there was a groud, a big one which was nice to just resting and resting you know. And you will find a big giant walls with small window shaped in it, that is a very good frame to click picture, rest aw well, I didn't bother, I was so tired on the way to Jantar Mantar I found a big India Flag and was feeling so much patriotic that I lost my energy in finding the source of it. Anyway enjoy. Look at the picture I'm sharing here, this wall was I'm talking about.

Naveen Kumar Reddy | May 31, 2018

It's a good place to visit. But it is not as big as the Jantar Mantar in Jaipur. So, you'll be disappointed if you have visited the Jantar Mantar in Jaipur. This also has an entry fee. You can enjoy sitting in the gardens. Visit it preferably during the winters because it's open and you'll come I'm contact with direct sunlight. If you visit it in the summer, visit in the evening.

The astronomical strucutres were very impressive. These devices even today can hold their own against modern instruments which makes them even more impressive. Spending time studying the scientific thought behind these instruments was very insightful. However, it is a place best visited when the weather is favorable - because the summer heat of Delhi was excruciating.

All in ONE | Jun 29, 2018

It is not a place where you can chill during day time for a long time. For couples it's good but not so relaxing. Privacy is not there. For family it's quite fun if you are visiting for the first time. Kids will have quite a good time. Overall time one should spend there is hardly 1 hour.

Praveen Sharma | Jun 20, 2018

Very good place to visit. Every man should visit this place once in life time. Very good achievement of our ancient scientists. If you want to explore New sciences dimension than visit this place at once. Hope everyone enjoyed like me so so much. Hence visit once in lifetime

Ghassan Beyrouthy | Jun 11, 2018

I was stunned with the scientific knowledge that the Jantar Mantar was built with, around the year 1720. 13 architectural astronomy structures outstandingly executed. The sun watch and the replica of constellations is a work of art. The visit needs half a day and it is in the open so a hat is a must and a water bottle. A guide is helpful to explain how the structures function and their design.

Akanksha Dwivedi | Jul 31, 2018

Over all it's a nice place to visit but not for too long. I'll explain the location in points, so that you'll know whether you want to visit this place or not. Good points as per me: 1. It's not crowded on weekdays 2. I'm a big nature fan and if you want a little glimpse of nature, you can visit this location and chill because this place is well maintained. Plants out here are in healthy condition. 3. It's clean and not noisy 4. No one would bother you much, if you want to relax for some time 5. Can click good photographs 6. You'll see an ancient clock here, with the help of shadow, one could tell the time. A few draw backs: 1. There is not much to do here 2. This place is not really big 3. Avoid this place in hot temperature

Shreyas P | Aug 4, 2018

The place has a lot of potential but its not at all well maintained. You can read the boards and try to understand the instruments but it will not strike you untill you have thoroughly analyzed the writing. There should be a guide who is capable of explaining the instruments in layman terms.

Mahbubul Hasan | Jul 14, 2018

It's a historical place. But if there is some demonstration.....how they worked with these in old days..... that would be a great experience. Otherwise seeing only the buildings ..... bring no interest. At least some pictures should be there. And there is no details description of it even.

AJAYKUMAR KAWALE | Jul 26, 2018

Nice place for curious n researchers. Great architecture and knowledge of astronomy is maintained in 18s era.which is itself the glorious history of Advanced Indian Astronomy. It is nowadays famous due to protests. Must visit !
