Jantar Mantar Delhi Travel Guide 2026

Delhi is famous for its historic forts, monuments and museums, but hidden among the busy streets of Connaught Place is a fascinating monument dedicated to astronomy and scientific observation — Jantar Mantar.

Built in 1724 by Maharaja Jai Singh II of Jaipur, Jantar Mantar is a historic astronomical observatory containing large-scale instruments designed to study the movement and position of celestial objects. Delhi Tourism notes that Jai Singh built similar observatories at Ujjain, Varanasi and Mathura as well.

Today, Jantar Mantar offers visitors a chance to see how astronomy was studied before modern telescopes and electronic instruments.

What is Jantar Mantar?

The name Jantar Mantar is derived from words associated with instruments and calculation/formulae. The Delhi observatory was designed as a collection of large astronomical instruments that could be used to make observations related to the Sun, stars and celestial positions.

Instead of using small portable instruments, Maharaja Jai Singh commissioned large masonry structures. Their size helped improve the precision of astronomical observations compared with smaller instruments available at the time.

The site is therefore an interesting combination of:

• Science
• Astronomy
• Architecture
• History
• Mathematics
• Heritage

History of Jantar Mantar Delhi

Jantar Mantar Delhi was constructed in 1724 under Maharaja Jai Singh II of Jaipur.

Jai Singh was deeply interested in astronomy and mathematical calculations. He believed that larger instruments could provide more accurate observations than the smaller instruments being used at the time.

He subsequently established similar observatories in other cities, including Jaipur, Ujjain, Varanasi and Mathura.

The Delhi observatory is therefore part of a larger scientific and architectural legacy created during the 18th century.

Why is Jantar Mantar Important?

Jantar Mantar is important because it shows how astronomers used large architectural instruments to study the sky before the widespread use of modern telescopes.

The structures were carefully designed according to astronomical principles.

The observatory demonstrates how architecture, geometry and astronomy could be combined to create practical scientific instruments.

UNESCO documentation on India's Jantar Mantar observatories describes these sites as important examples of pre-telescopic masonry astronomical instruments.

Major Instruments at Jantar Mantar

The observatory contains several fascinating instruments, each designed for particular astronomical observations.

Samrat Yantra

The Samrat Yantra is a giant sundial-like instrument designed to measure astronomical time and celestial positions.

Its massive triangular structure and curved scales demonstrate the impressive scale of 18th-century astronomical engineering.

Jai Prakash Yantra

The Jai Prakash Yantra consists of large hemispherical structures.

These instruments were designed to represent the celestial sphere and help determine the position of celestial objects.

The instrument is particularly interesting because visitors can walk around and observe its large-scale astronomical markings.

Ram Yantra

The Ram Yantra consists of cylindrical structures with a central pillar.

It was designed for measuring the altitude and azimuth of celestial objects.

Its open design makes it one of the most visually interesting instruments at the observatory.

Mishra Yantra

Mishra Yantra is another important group of structures at the observatory.

The different components were designed for astronomical calculations and observations involving celestial bodies.

Digamsa Yantra

The Digamsa Yantra is associated with measuring angular distances in relation to the north direction.

It demonstrates how the instruments at Jantar Mantar were designed for specific astronomical calculations.

How Did Jantar Mantar Work?

The instruments at Jantar Mantar used basic principles of:

• Geometry
• Shadows
• Angles
• Earth's rotation
• Celestial coordinates
• Solar movement

For example, the position of a shadow could be observed against carefully marked scales to determine time or celestial measurements.

Large structures provided a way to make measurements with greater precision than smaller instruments.

UNESCO documentation describes instruments such as Ram Yantra, Samrat Yantra and Jai Prakash Yantra as part of India's historic tradition of large-scale, pre-telescopic astronomical observation.
