Truly amazing architecture for calculating the time.

Ram Yantra was named after the grand father (Raja Ram Singh) of Maharaja Jai Singh. This was used to be measurement of horizontal and vertical angle of celestial bodies. It is counted amongst Jai Singh's medium precision instruments. This is a cylindrical instrument consisting of two large buildings open to the sky.

Ticket priced at Rs 15 Per person for Indians and Rs 200 for Foreigners. Its a place not to be missed for architecture and Science ! Make sure you have done a small research about the logic used a few technical terms. Although things are written clearly, but for people who really want to understand whats the science behind it, its good to understand some things through the internet. Otherwise, just sit back, explore and enjoy !

(Translated by Google) The Rama Yantra and Jai Prakash Yantra describe the movement of celestial bodies. Ram Yantra is circular (Original) राम यंत्र और जय प्रकाश यंत्र खगोलीय पिंडों की गति के बारे में बताता है। राम यंत्र गोलाकार बने हुए

It is must visit place of delhi and also part of any tour package in Delhi. We need atleast a half day to know nicely about its scientific importance and old science of India. If we visit these place with a local guide then we can get more informations about this.

Place to learn astronomy from historical architecture.

This was an astronomical instrument used by the King Sawal Jai Singh of Jaipur.

Jantar Mantar is located in the modern city of New Delhi. 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. 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. 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.

Ancient monument you can click nice photos here , place is located inside jantar mantar

Nice

Visit it to know how simple knowledge can still give precision engineering and information.

Its very helphul to the astronomers to find out the zenith distance and the altitude of the sun

Amazing one

Part of the Jantar Mantar complex, ahving it's own technical identity.

Cylindrical shaped two large construction open to sky. It is used to measuring the altitude of sky.

This is situated inside the Jantar Mantar tourist spot of the capital. This place is not so big and so famous but it has its own importance. The Ancient time Telling watch is installed here that is called Jantar Mantar. It is designed in such a way that it reflects the sunlights and tells the time . All details about it's functioning are encraved on the board...

Nice

Waste of time.

The Jantar Mantar is an equinoctial sundial, consisting of a gigantic triangular gnomon with the hypotenuseparallel to the Earth's axis. On either side of the gnomon is a quadrant of a circle, parallel to the plane of the equator. The instrument is intended to measure the time of day, correct to half a second and declination of the Sun and the other heavenly bodies. There are four Jantar Mantars in India, of which the largest is in Jaipur which features many instruments along with the world's largest stone sundial.The Vrihat Samrat yantra is a sundial that can give the local time to an accuracy of 2 seconds.It is a UNESCO World Heritage Site.

Precision instruments of olden days.. Reminds you of a protractor and set square.. But blown out of proportion on the ground!

Good.

No need to appraise this fantastic Monumental legacy of Indian Astronomers, Perfect, well maintained, accurate with high precision, kept intact.

I don't know what the techniques they have used at that time to built this monument. It is perfectly constructed by using perfect calculation and all... Salute to the architect who built this monument...

Jantar Mantar is located in 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, must visit place at least once.

The Rama Yantra is used to observe the position of any celestial object by aligning an object in the sky with both the top of the central pillar, and the point on the floor or wall that completes the alignment. The 4 distinct instruments within the observatory of Jantar Mantar in New Delhi: the Samrat Yantra, the Jayaprakash, Rama Yantra and the Misra Yantra. The objective behind the construction of these observatories was to assemble astronomical data and to accurately predict the movement of the planets, moon, sun, etc. in the solar system. It was one of its kind at the time it was built. By the year 1867, when India was under the British Raj, the observatory had undergone considerable decay

It's a very beautiful place to visit. This place can't be missed for its architecture, science and beauty

Ram Yantra is nice place to atleast visit one times in life. Ram yantra was named after the grand father (Raja Ram Singh) of Maharaja Jai Singh. This was used to be measurement of horizontal and vertical angle of celestial bodies. It is counted amongst Jai Singh's medium precision instruments. This is a cylindrical instrument consisting of two large buildings open to the sky.

If u r curious to know ancient methods of knowing time , solar system etc... Then this place is for u • jantar mantar is not in a large area

Great Indian heritage...... visit 1 hours.

Average place.....

Ram Yantra in Jantar Mantar is the device used for measuring the altitude of stars. It is a cylindrical instrument, consisting of two large buildings open to the sky. The beauty of the instrument is, that it gives us direct readings. Basically the instrument consists of two circular stone building. If we unite them together, it becomes one instrument. This way one is complimentary to the other. They are constructed at a reasonable distance. In the centre of the instrument a perpendicular rod is fixed, which is of the same height of the building itself. Twelve stone triangles are fixed above the ground. These triangular stone slabs are graduated from 90 degree to 45 degree, while 45 to 0 degree the graduations are on the circular wall. This is an instrument by which we come to know the movement of stars. It is based on the horizon and zenith system

We had read about Jantar Mantar in books and heard about it in this school and when I experienced it myself, I realized that even today we can keep our heritage, our historical things alive. . There is a lot of thinking about it which we came to know after visiting the front and it is a very good place, it is a very beautiful place.

The Ram Yantra, as part of Jaipur's Jantar Mantar observatory, offers a unique glimpse into ancient astronomical practices. It's an intriguing piece of history that showcases the advanced scientific knowledge of its time. Visitors interested in astronomy and history can appreciate the architectural precision and the insights it provides into celestial measurements, making it a noteworthy stop within the Jantar Mantar complex.

This is inside the Jantar Mantar complex, and in front of the Ashoka Hotel. Good view from the Hotel lobby/window. A must visit for architecture lovers!!
