Jantar Mantar is an astronomical observatory located in Jaipur, the capital city of the Indian state of Rajasthan. Built by Maharaja Sawai Jai Singh II in the early 18th century, it is one of the five observatories constructed by the ruler in different parts of India. Jantar Mantar in Jaipur is the largest and most well-preserved among these observatories, and it has become a popular tourist attraction and a UNESCO World Heritage site. The name “Jantar Mantar” is derived from the Sanskrit words “yantra” (meaning instrument) and “mantra” (meaning formula or calculation).

History: From its concept to its existence

The Jantar Mantar in Jaipur covers an area of about 18,700 square meters and consists of a collection of astronomical instruments. These instruments were designed to measure time, predict eclipses, and observe celestial bodies such as the sun, moon, and stars. The observatory features 19 main instruments, including the world’s largest stone sundial, which is a major highlight of the site.

From a thought to its existence

The sundial, known as the Samrat Yantra or the Supreme Instrument, is a massive stone structure standing at a height of 27 meters. It is positioned at an angle that aligns with the Earth’s axis, allowing it to accurately measure time to the precision of two seconds. The Samrat Yantra can be used to determine the local time, as well as the declination of the sun and the position of various constellations.

Another prominent instrument at Jantar Mantar is the Jai Prakash Yantra, which consists of two concave hemispheres with markings representing the celestial sphere. This instrument is used to measure the azimuth and altitude of celestial bodies and is particularly useful for observing the positions of stars and planets.

The Jaipur observatory also includes the Ram Yantra, a cylindrical structure with an inclined ramp and an observation platform. The ramp has markings that allow observers to measure the azimuth and altitude of celestial bodies as they move across the sky.

The observatory complex also houses several other fascinating instruments, such as the Chakra Yantra (a circular instrument for measuring the azimuth), the Narivalaya Yantra (used to measure the meridian and altitude of celestial bodies), and the Digamsha Yantra (a hemispherical instrument for determining the azimuth of the sun).

Each instrument at Jantar Mantar is meticulously designed and calibrated to provide accurate astronomical measurements. The observatory reflects the deep understanding and knowledge of astronomy possessed by Maharaja Sawai Jai Singh II, who was not only a ruler but also a scholar and an avid astronomer.

The construction of Jantar Mantar began in 1728 and was completed in 1734. Maharaja Sawai Jai Singh II employed skilled craftsmen and astronomers to build the instruments using locally available materials such as stone and marble. The observatory’s architectural style is a blend of Indian and Islamic influences, and its precision and scientific significance have made it a landmark in the field of astronomy.

Jantar Mantar has not only served as an astronomical observatory but also as a center for studying and advancing the field of astronomy. Scholars and astronomers from various parts of the world have visited the site to study the instruments and conduct research.
