What is Jantar Mantar Delhi?

Jantar Mantar Delhi is an astronomical observatory built by Maharaja Jai Singh II of Jaipur in the 18th century. The name Jantar Mantar means “instrument for calculation” in Hindi. Jantar Mantar Delhi is one of the five observatories built by Maharaja Jai Singh II in India. The other four are located in Jaipur, Ujjain, Varanasi, and Mathura. Jantar Mantar Delhi was built between 1724 and 1730 as a part of Maharaja Jai Singh II’s quest to reform the calendar and astronomical tables. He was also interested in studying the celestial phenomena and improving his knowledge of astronomy.

Jantar Mantar Delhi consists of 13 structures that are designed to measure time, determine the positions of the sun, moon, and planets, predict eclipses, and observe the equinoxes and solstices. These structures are made of brick, plaster, and stone and are painted in red and yellow. They have different shapes and sizes, ranging from a giant sundial that is 27 meters high to a hemispherical instrument that is 4 meters in diameter. Each structure has a specific name, meaning, and function. Some of the structures are unique to Jantar Mantar Delhi and are not found in any other observatory.

What are the structures inside Jantar Mantar Delhi?

The structures inside Jantar Mantar Delhi are:

Samrat Yantra:

This is the largest structure in Jantar Mantar Delhi and is also known as the “King of Instruments”. It is a giant sundial that measures time based on the position of the sun. It has a triangular gnomon that is 27 meters high and two quadrants that are 15 meters long each. The gnomon casts a shadow on the quadrants that indicates the time of the day with an accuracy of two seconds. The Samrat Yantra can also measure the declination of the sun, which is the angle between the sun and the equator.

Jai Prakash Yantra:

This is a hemispherical instrument that measures the coordinates of celestial bodies. It has two concave bowls that are 4 meters in diameter each. The bowls have markings that represent the celestial coordinates such as latitude, longitude, altitude, and azimuth. A metal rod is suspended from a pole at the center of each bowl. The rod points to a celestial body and its shadow falls on the bowl. By reading the markings on the bowl, one can determine the coordinates of the celestial body.

Ram Yantra:

This is a cylindrical instrument that measures the altitude and azimuth of celestial bodies. It consists of two circular walls that are 5 meters high and 11 meters in diameter each. The walls have openings at different heights that allow the observation of celestial bodies. A metal ring is attached to a pole at the center of each wall. The ring points to a celestial body and its shadow falls on the wall. By reading the markings on the wall, one can measure the altitude and azimuth of the celestial body.

Misra Yantra:

This is a composite instrument that consists of five smaller instruments. It was added by Maharaja Madho Singh II of Jaipur in 1850. The five instruments are:

Dakshinottara Bhitti Yantra: This is a wall instrument that measures the meridian altitude of celestial bodies.

Niyat Chakra: This is a circular instrument that measures whether a celestial body is in the northern or southern hemisphere.

Krantivritta Yantra: This is a circular instrument that measures whether a celestial body is in ascension or declination.

Raj Yantra: This is an instrument that measures local time.

Shastansh Yantra: This is an instrument that measures one-sixtieth part (one degree) of an arc.

Other structures:

There are eight other structures in Jantar Mantar Delhi that have different functions and names. They are:

Narivalaya Yantra: This is an instrument that measures the local time in different seasons.

Rashivalaya Yantra: This is an instrument that measures the zodiac signs of celestial bodies.

Digyansa Yantra: This is an instrument that measures the azimuth of celestial bodies.

Chakra Yantra: This is an instrument that measures the declination of celestial bodies.

Kapali Yantra: This is an instrument that measures the coordinates of celestial bodies in a stereographic projection.

Laghu Samrat Yantra: This is a smaller version of the Samrat Yantra that measures time with less accuracy.

Unnatasha Yantra: This is an instrument that measures the meridian altitude of celestial bodies at different latitudes.

Dhruva Darshak Pattika: This is an instrument that locates the pole star.

What is the history of Jantar Mantar Delhi?

Jantar Mantar Delhi was built by Maharaja Jai Singh II of Jaipur, who was a great patron of astronomy and mathematics. He was also a ruler of a large kingdom that spanned across Rajasthan, Gujarat, and parts of Madhya Pradesh. He was appointed by Emperor Muhammad Shah of the Mughal Empire to reform the calendar and astronomical tables. He was also interested in studying the celestial phenomena and improving his knowledge of astronomy.

Maharaja Jai Singh II was inspired by the Ptolemaic astronomy and Islamic astronomy. He studied various texts and instruments from different cultures and regions. He also consulted with scholars and experts from India and abroad. He decided to build five observatories in India, one in each of his capitals: Delhi, Jaipur, Ujjain, Varanasi, and Mathura. He chose these locations because they were situated along the same meridian and had different latitudes. He also wanted to compare his observations with those made by other astronomers around the world.

Jantar Mantar Delhi was the first observatory to be built by Maharaja Jai Singh II. He started its construction in 1724 and completed it in 1730. He used his own funds and resources to build it. He also employed skilled artisans, masons, carpenters, and painters to construct it. He supervised the design, layout, alignment, and calibration of the structures. He also personally tested and verified the accuracy and precision of the instruments.

Jantar Mantar Delhi was used by Maharaja Jai Singh II and his successors for astronomical observations and calculations. They recorded their findings and published them in various journals and books. They also shared their data and discoveries with other astronomers around the world. Jantar Mantar Delhi was a center of scientific learning and exchange for many years.

However, Jantar Mantar Delhi gradually fell into disuse and decay after the decline of the Mughal Empire and the rise of British rule in India. It was neglected and vandalized by people and nature. It was also encroached upon by buildings and roads. It lost its original function and glory.

Jantar Mantar Delhi was restored by British and Indian authorities in the 19th and 20th centuries. It was declared a national monument in 1948 by the Government of India. It was also inscribed as a UNESCO World Heritage Site in 2010 as part of the group “Jantar Mantar”. It is now maintained by the Archaeological Survey of India (ASI) as a museum and a tourist attraction.

Jantar Mantar Reviews

Lets say you found yourself in New Delhi and you planned to visit the great and plush market of Connaught Place . You went there, and shopped around,ate at the awesome food joints & coffee houses which are present in the area, and you found yourself craving a place to go and sit and relax & be one with the nature. Most people will say they prefer the central park of CP but lemme give you an alternative,the huge and sprawling mystery architecture that is JANTAR MANTAR. Located at the western part of CP not too far from the amazing Madame Tussauds wax museum,the complex of JANTAR MANTAR is an observatory. Basically under the patronage of mughals, It was built as an observatory for calculation of time and the passage of the day as the sun goes a full circle from east to west. The area has a park and rows of trees where you can sit and relax. Have a good time away from the hustle and bustle of the overcrowded market. You can find a number of refreshments available outside the gate and then you can enjoy the views of the mysterious structures. There are 4 major observatories which were used a few centuries ago. The most recognizable is the Misra observatory or yantra which could be recognized as it has a similar structure like an inverted heart. The place is quite serene and also very photogenic,you can snap some amazing pictures here . If you want a somewhat peaceful place to maybe take in the shopping that you did or amazing meals that you had , come here and try to walk around the premises.Maybe you will discover something,or more likely you will just find yourself getting photographed. I am just kidding,no personal discoveries can be be achieved here, but maybe you can discover someone else if you get lucky.???? Go and visit the place, believe me you will enjoy it wholeheartedly but dont forget to bring the DSLRs because then you will be mad! Peace out! ps- I have included some snaps of mine so you can see the photogenic nature of the place!
Jantar Mantar is just shy of 1 Km from Cannaught place,after a short walk we were there and nowadays they even have a ticketing system which is both online and offline. As you enter the premise the first structure to the right is “Misra Yantra”. This is that structure which I saw numerous times in my textbooks, a curvature wall structure with standing boundaries at both sides. Avantika told me this is a set of five instruments that when worked together in harmony determines the exact moment of noon in multiple cities across the globe. Yes, my friends this is a living structure of Indian heritage, the Vedic mathematics. She further elaborated that this place also serves as a place for peaceful protests due to its close proximity to the Parliament. That was quite fascinating to me that this place had such a strong relation with our ancient history and today’s societal affairs. With further research I found out that there are other observatorieslike this that are present in the country which were constructed in Jaipur, Ujjain, Varanasi and Mathura.While four of these landmarks still stand today, the one in Mathura, unfortunately, got destroyed in the 1850s. Standing in front of these structures takes you back to those moments when they were being built and mesmerizes you with almost magic like Indian science before the age of technology. That, how this ancient mathematics was deeply integrated within our society, planetary observations and zodiac signs. While roaming she tried to explain me the signboards which were in front of each observatory which were installed there, If I recalled their names were :
Jantar mantar is situated on the parliament Street near Connaught place. Visit to this place is a must as it tells us about how Indians wanted to know about the astronomical phenomenon from an early age. I went to Jantar Mantar with my friends and it was really an unforgettable experience which gave us a glimpse of our country's proud history. Nowadays, Jantar Mantar is also a place where crowd gathers for various events. Owing to it's central location at the heart of capital city, it is naturally a center for a lot of events and other activities. A lot of runs are also organized from Jantar Mantar.
The Jantar Mantar is a collection of nineteen architectural astronomical instruments built by the King Sawai Jai Singh II. It features the world's largest stone sundial. Easier Way To Plan Your Itinerary with time constraint Hawa Mahal, Jantar Mantar, Albert Hall Museum and the City Palace are in close proximity to each other. Jal Mahal, Amer Fort, Jaigarh Fort, Hanuman temple and the Jaipur Step Well are in close proximity to each other. Make sure to start your day really early if you are planning to cover these 5 places on the same day. Patrika gate is near to the Jaipur Airport, you can plan your Itinerary accordingly.
One weekend I was in Delhi to attend a presentation of a networking organisation. When It got over, I found that the place which Delhi has turned into an unofficial protest ground is not far away. Yes, that's the Jantar Mantar of new Delhi. So, me and my friend, quickly planned a tour of Jantar Mantar. How to reach: If you are in Delhi, metro would be the best option. The nearest metro station is Pragati maidan. Budget & timings: ₹5/indian ₹100/foreigner ₹25/camera charge Opening time: 6 am to 6 pm Duration: Half an hour Mobile allowed inside, without any fee.
