We might be hearing regularly in news, near jantar Mantar protests happened -so to see the heard one we can go once- not allowed inside to see -only from outside we can see the monuments

Jantar Mantar is located in the modern city of New Delhi. "Jantar Mantar" means "instruments for measuring the harmony of the heavens". It consists of 13 architectural astronomy instruments. The site is one of five built by Maharaja Jai Singh II of Jaipur, from 1723 onwards, revising the calendar and astronomical tables. Jai Singh, born in 1688 into a royal Rajput family that ruled the regional kingdom, was born into an era of education that maintained a keen interest in astronomy. There is a plaque fixed on one of the structures in the Jantar Mantar observatory in New Delhi that was placed there in 1910 mistakenly dating the construction of the complex to the year 1710. Later research, though, suggests 1724 as the actual year of construction. Its height is 723 feet (220 m).

Good Historic Monument but its almost destroyed. Nothing much to see.

Structure made me realize Astrology knowledge of ancestors was magnificent.

20₹ tickets for online 25₹ for offline.
If you come nearby then you can visit otherwise i don't suggest to plan just to come here.

Jantar Mantar in Delhi is an awe-inspiring testament to human curiosity and scientific prowess. This UNESCO World Heritage Site is a collection of astronomical instruments that were ahead of their time when built in the 18th century

Not good, thery closed main building from inside and nothing is therr for tour except a grass loan

It holds a lot of history but the place not highly maintained it is at ok stage. You cannot go inside the structure to see the area. Different section and you can read about it. Try to avoid sunny days. You have to pay a small token amount before entering as they are taking it as maintaince fee. Worth one visit or if you are visiting after long time (years) once again then you will definitely notice the differences

Jantar Mantar an architectural astronomy placed in New Delhi.

It consists of total 13 architectural astronomy instruments.

You can buy tickets here directly and its really cheap, no need of advance booking via online the rate really differs.

I loved this place hope you will love it too.

Standing tall and majestic, it is a UNESCO World heritage site and a symbol of India's rich history.while exploring the Qutub Minar complex, I also discovered the stunning Quwwat-ul-Islam Mosque and the Iron Pillar. Visiting Qutub Minar was not only a journey through time but also a chance to appreciate the architectural brilliance of the past

Marvelous Indian heritage. And its incredible to know the effectiveness of these buildings (instruments) till date.

I'm the only tourist in city but still I'm paying 10 times more than locals. Anyway place is nice

Thus heritage could have been preserved well. We went with the kids to show them the primitive ways of time keeping etc, but there were no guides who can show us around.
Ideally, there should be official guides who can show people around. The charges I heard is 1000 and as such no one gives and thus there is no guide around.

The charges if reasonable, people will hire them and this place would be fun

It was nice but public utilities were missing.
All other areas are closed it is just a park now

Jantar Mantar lies at the entrance to CP so if you are visiting Connaught Place you should visit here. Well maintained and beautiful place. It was drizzling that day so it made the place look more beautiful.

Jantar mantar more of an archaeological site, for a person who is not much interested in astrology, there's nothing more than an old historical site which is not in a good state
If someone comes with pre preparation he'll love this place and the instrument

Amazing techniques used in the past. Hire the security as guide to help you understand what each device is used for. I hope the devices are restored and made working to understand them in a better way.

Constructed in 1724 by Maharaja Jai Singh of Jaipur, Jantar Mantar is an astronomical observatory. Fascinating for their ingenuity, the instruments at Jantar Mantar can no longer be used accurately because of the tall buildings around. However, a visit to admire the science of Indian astronomy makes it one of the most visited tourist attractions in Delhi.

So the person who conceptualized this place would not have been very proud of it's current status.
It has apparently a more precise sun dial compared to the one in Jaipur. But to everyone's disappointment one can only view it as a model. Most of it is now dysfunctional and the nearby tall buildings are the major reason behind it.
Now it is primarily used for political processions. However if detailed history is your zone.don't miss it.
For the casual travelers it can be bypassed for the more beautiful locations around Delhi.
Guides will be difficult to get hold of unless you have a foreign tourist with you. ;)
Have a good time.learning a piece of scientific history.

One time watch place. Here you see only a red shaped clock thing that you seen in most of the photos.
You can sit some time in the park and that's it.entry fee rs20 online or rs25 in cash

दिल्ली का जन्तर मन्तर एक खगोलीय वेधशाला है। अन्य चार जन्तर मन्तर सहित इसका निर्माण महाराजा जयसिंह द्वितीय ने 1724 में करवाया था। यह इमारत प्राचीन भारत की वैज्ञानिक उन्नति की मिसाल है। जय सिंह ने ऐसी वेधशालाओं का निर्माण जयपुर,  उज्जैन,  मथुरा और वाराणसी में भी किया था। दिल्ली का जंतर-मंतर समरकंदकी वेधशाला से प्रेरित है। मोहम्मद शाह के शासन काल में हिन्दु और मुस्लिम खगोलशास्त्रियों में ग्रहों की स्थिति को लेकर बहस छिड़ गई थी। इसे खत्म करने के लिए सवाई जय सिंह ने जंतर-मंतर का निर्माण करवाया। ग्रहों की गति नापने के लिए यहां विभिन्न प्रकार के उपकरण लगाए गए हैं। सम्राट यंत्र सूर्य की सहायता से वक्त और ग्रहों की स्थिति की जानकारी देता है। मिस्र यंत्र वर्ष के सबसे छोटे ओर सबसे बड़े दिन को नाप सकता है। राम यंत्र और जय प्रकाश यंत्र खगोलीय पिंडों की गति के बारे में बताता है।
राजा जयसिंह द्वितीय बहुत छोटी आयु से गणित में बहुत ही अधिक रूचि रखते थे। उनकी औपचारिक पढ़ाई ११ वर्ष की आयु में छूट गयी क्योंकि उनकी पिताजी की मृत्यु के बाद उन्हें ही राजगद्दी संभालनी पड़ी थी। २५जनवरी,  १७०० में गद्दी संभालने के बाद भी उन्होंने अपना अध्ययन नहीं छोडा। उन्होंने बहुत खगोल विज्ञानं और ज्योतिष का भी गहरा अध्ययन किया। उन्होंने अपने कार्यकाल में बहुत से खगोल विज्ञान से सम्बंधित यंत्र एवम पुस्तकें भी एकत्र कीं। उन्होंने प्रमुख खगोलशास्त्रियों को विचार हेतु एक जगह एकत्र भी किया। हिन्दू, इस्लामिक और यूरोपीय खगोलशास्त्री सभी ने उनके इस महान कार्य में अपना बराबर योगदान दिया। अपने शासन काल में सन् १७२७ में, उन्होंने एक दल खगोलशास्त्र से सम्बंधित और जानकारियां और तथ्य तलाशने के लिए भारत से यूरोप भेजा था। वह दल कुछ किताबें, दस्तावेज और यंत्र ही ले कर लौटा। न्यूटन, गालीलेओ, कोपरनिकस और केप्लेर के कार्यों के बारे में और उनकी किताबें लाने में यह दल असमर्थ रहा।

The Jantar Mantar in New Delhi is a complex that includes a number of different structures used for astronomy observations. Commissioned by Muhammad Shah, the Mughal emperor, the structures were actually constructed by Maharaja Jai Singh II from Jaipur, Rajasthan (if you visit Jaipur, they have an even nicer Jantar Mantar).

The thirteen different instruments are all used for different purposes in figuring out sun, moon, and planet cycles, and other astronomy measurements.

यह इंडिया का एरिया और यहां कोई किसी की नहीं सुनता लोग यहां धरने देने आते हैं अपनी मांगों को लेकर इसलिए मुझे अच्छा लगा हमें अच्छा लगा हिंदुस्तान में कुछ जागरूक लोग भी है

The primary purpose of the observatory was to compile astronomical tables, and to predict the times and movements of the sun, moon and planets. Some of these purposes nowadays would be classified as astronomy.

Completed in 1724, the Delhi Jantar Mantar had decayed considerably by 1867. The Ram Yantra, the Samrat Yantra, the Jayprakash Yantra and the Mishra Yantras are the distinct instruments of Jantar Mantar.

This is a place. Built to see the sun watch. And only those persons who knew how to know the time by the shadow can understand there architecture. For others it's like nothing to see. But as children read it on their books. So everyone should once go there for an experience only. But there is Nothing interesting to see.

Huge Time observatory near CP (again) :) Recommended to visit with a tour guide as d monuments are instruments in themselves and would b better explained by d guide. Otherwise one would just gaze at dem in wonder without knowing their functioning.

Jantar mantar is the bunch of monument which actually tells that the ancient Indians science was very much forward than other countries. In this the architectures tells positions of the planets and the stars. These also tells the exact time even these architectures were built in 16th century.

What happens to all historical place in Delhi.why government is ignoring such an old monument.such a shame from team who are managing this historical monument.

Delhi Jantar Mantar is in dilapidated condition as compared to well maintained Jaipur one. Public coming here do not get any idea about what it is and leads to scribbling and damaging it further

Money is taken for entry, but it is in shambles. What ever was built and kempt is not the way it has to be. Public has left most of the site in a very critical condition. The archeological survey of India team should renovate this monument before it is too late.
