This astronomical observatory is regarded as the largest of the five built in Jaipur, New Delhi, Ujjain, Varanasi and Mathura. It also has the world’s largest sundial.

Derived from the Sanskrit, terms ‘Yantra’ and ‘Mantra’ which means instruments and formula, it slowly changed into Jantar Mantar (Jantar means magical).

This exquisite structure is the most suitable place for a tourist with the unquenching thirst to know about the universe.


This astronomical observatory took its origin from the ardent desire of Maharaja Jai Singh II, the founder of the pink city to know more about the universe and to use this place to sit with other scholarly astronomers such as P.T Kedar Nath.

 So he studied the subject of astronomy and constructed five different observatories around North India.

 Renovations were done time and again to this observatory.

If has various devices to give accurate measurements of time , declination of the sun, position of the constellation and many other astronomical phenomena.

This had a proper functioning only for seven years as they failed to derive précised astronomical observations.

Architectural Elegance

There are 14 major geometric devices measuring time, tracking constellations and noting the orbits around the sun.

To look into the mysteries of the universe there are the structures within the Jantar mantar like Samrat yantra, Hindu  Chhatri and the Jai Prakash Yantra.
