This video is a documentary on Jantar Mantar history and working of astronomical instruments like Laghu Samrat Yantra (Small Sun Dial), Vrihat Samrat Yantra (Largest Sun Dial), Jai Prakash Yanthra, Rashi Valaya Yanthra and Ram Yanthra.
The name jantar is derived from yantra, a Sanskrit word meaning instrument and mantar from mantrana another Sanskrit word which means calculate. Jantar Mantar literally means 'calculating instrument
The construction if the monument started in 1720 and was completed in 1734. The monument features instruments operating in each of the three main classical celestial coordinate systems,
the horizon-zenith local system, the equatorial system, and the ecliptic system.
Jantar Mantar is a Stone Observatory. Metals Shrink and expands, but Stone wont and is not affected by any season
Vrihat Smarat Yantra
Vrihat Smarat Yantra is largest sundial in the world. The Vrihat Samrat Yantra, which means the "great king of instruments", is having a height of 88 feet (27 m). It is placed at the center of Jantar Mantar observatory. This instruments works similar to the Small Sundial, but has a precision of two seconds. The shadow of the triangular wall of the yantra, which is positioned in the north-south direction with an angle identical to the latitude of this location, travels equal distances in equal intervals of time, on the eastern and western quadrants. This movement is standardized to calculate and interpret the local time.
Laghu Samrat Yantra
The smaller sundial at the monument,This sundial can calculate time upto an accuracy of 20 seconds. The ramp of this sundial points towards the North Pole, and hence Jaipur time can be easily calculated from the position of ramp’s shadow on the fine divisions of the carved scale. The shadow of the triangular wall of the yantra plus the reference time tells the local time.
Jai Prakash Yantra
This Yanthra consist of two hemispherical bowl like sundial with marked marble slabs that map inverted image of sky.This gaps are added to allow the observer to move inside the instrument,
This missing portion in this part is recreated next to this. In the middle you can see a iron ring which represents sun. The inverted image of the sky falls on the slabs and the movement of the inverted shadows help to detect the elevation, azimuth, hour angles and exact position of heavenly bodies.
Rashi Valaya Yantra.
Each of the 12 instruments is associated with one of the 12 signs of the zodiac.The purpose of the instrument is to calculate the sidereal time.
Ram Yanthra
Ram Yantra measures elevation and azimuth of Sun and planets. The instrument comprises a pair of tube-shaped structures, open to the sky. Each structure has a pole of equal height at the center. Scales indicating angles of altitude and azimuth of extra-terrestrial bodies are inscribed inside the walls of these structures. The circular ring near the roof of the instrument has 360 degree scale for the azimuth, along the circumference. Each degree division is further divided into minute divisions and the smallest division is one fifth of a degree. Ram Yantra is only seen in Jantar Mantar of Jaipur and New Delhi.
1. Chakra Yantra
2. Dakshin Bhitti Yantra (measures meridian, altitude and zenith distances of celestial bodies)
3. Digamsha Yantra (used to measure azimuth of the sun, and to calculate the time of sunrise and sunset forecasts)
4. Disha Yantra
5. Dhruva Darshak Pattika (observe and find the location of pole star with respect to other celestial bodies)
7. Kapali Yantra (measures coordinates of celestial bodies in azimuth and equatorial systems, any point in sky can be visually transformed from one coordinate system to another)
8. Kanali Yantra
9. Kranti Vritta Yantra (measures longitude and latitude of celestial bodies)
11. Misra Yantra (meaning mixed instrument, it is a compilation of five different instruments)
12. Nadi Valaya Yantra (two sundials on different faces of the instrument, the two faces represent north and south hemispheres, the accuracy of the instrument in measuring the time is less than a minute)
13. Palbha Yantra
16. Shastansh Yantra (to measure the zenith distance, declination, and the diameter of the Sun.)
17. Unnatamsa Yantra
19. Yantra Raj Yantra (a 2.43-metre bronze astrolabe, one of the largest in the world, used only once a year, calculates the Hindu calendar)
For information only, the Jantar Mantar is not the largest sundial in the world, although it is for sure one of the most spectacular and large, as well as ancient, with a great historical value, located within a superb compound of astronomical instruments. Nevertheless the largest sundial of the world is located in Zaragoza (Spain) and has been acknowledged as such by the Guinness World Record organization some years ago. It is larger than the Jaipur's one, although not as interesting in historical terms, but it also has an outstanding accuracy.
Thank You for the update. It was a new information to me.
This is how was India ❤❤❤❤...
Great, informative video! So good, I had to hit subscribed. I never knew of this attraction, but it's on the list now! Thank you for sharing!
Thank you
I would love to see this in person
Please do visit. India is Incredible🇮🇳
Saw this on an episode of 'Around the World in 80 Treasures'; a tour of some of the amazing places in India, I was shocked to hear it was built 1740s?! - Looks more like 20thC. Fascinating place 💜💜💜 (Some incredible & very beautiful places in India, but I'm not good with heat or crowds, so I like watching videos instead! :) x
Hope this video series will be interesting to you

this is waste

Any specific reason?
@@Indianglobetrotting Most likely this person was just having a bad day, and wanted to ruin someone else's day by denigrating this video, which was informative, if not especially well organized and without much connection between the narration and the images being recorded by the camera, except to name the structure, in most cases. Showing the iron "ring" suspended over the deep dishes was unusually helpful, but sundials have to be "adjusted" according to what is referred to as the "equation of time," which provides the necessary correction for the indicated time, depending on the day of the year, and this video did appear to try to introduce the idea, but not very well.
