"In 1728, Sawai Jai Singh II, rajah of Jaipur, dispatched his emissaries across the globe to gather the most accurate astronomical data possible. When they returned, Jai Singh ordered the construction of the original Jantar Mantar complex in New Delhi, a monumental astronomical observatory constructed entirely out of stone and based on the astronomical tables of the French mathematician Phillipe de la Hire. In all Sawai Jai Singh built a total of five observatories, with the largest being this later construction of the Jantar Mantar in his hometown of Jaipur. Among the stone instruments Jai Singh constructed was the Samrat Yantra, a 73-foot-tall sundial which remains the largest ever built. Though indistinguishable in design from other sundials of the day, it was far and away the most accurate. Its two-second interval markings are more precise than even de la Hire’s table. The smaller but older (and pink) version of the Jantar Mantar can be seen in New Delhi." - ATLAS_OBSCURA

"Janta Mantar, a Jaipur park for the space-and-time-inclined, wasbuilt in the early 1700s by the Maharaja Singh.The UNESCO World Heritage site, located in the old city, contains20 large stone astronomical instrumentsdesigned to assist scientists who wereobserving the heavens with their bare eyes. The huge tools monitorcelestial happenings and are still in used today for agricultural predictions. One can walk between the impressive apparatuses and imagine the 18th-century scientists of the royal court plotting and charting impossible distances and paths."

A truly amazing place to visit. The place gives you the history of how in spite of being a ruler, the local king was so interested in science. He has spent much of his wealth trying out different experiments to build sun dials of different types that give the exact details of the time using sunlight. The place is full of sun dials of different types. If you are planning to visit the place, I would recommend the first head directly to the theater that explains the history and details about how each dial works. This will give you details about how you can view and understand the multiple sun dials that are built in this place. A wonderful experience without any doubt.

Best place for learning more mechanics and calculation involving celestial bodies. Both kids and adults can enjoy the place. Would be best to hire a guide if you’re like me - lazy to read information. Speaking of which there are information boards everywhere providing great information.

It is a nice place to visit. You can roam around freely it is a big garden-like structure. There's not much to explore around the place. It is mainly based on displaying the ways of learning time and zones by different methods.

It was a great place to learn the history of early mathematics and astronomy/ astrology (the kings believed in both) of Jaipur. The sun dials are terrifyingly accurate (we cross checked with our phones to make sure). The tickets were fairly cheap and the guide was very knowledgeable. Don’t give this a miss if you’re in Jaipur.

Visiting Jantar Mantar in Jaipur was truly an unforgettable experience and a fascinating glimpse into India’s historical brilliance. This UNESCO World Heritage site showcases the scientific and astronomical achievements of our past. The experience was made even more enriching with a guide, who explained the incredible instruments and their functions. We learned how the Raja measured time, determined the astrological zodiac signs of individuals born in the current era, and even had a system to recognize the zodiac sign of a newborn along with suggesting suitable first names as per their zodiac—a remarkable blend of science and tradition. Among the instruments, we saw timepieces with incredible precision, including a smaller clock with a 20-second margin and a larger one with just a 2-second difference. The guide also demonstrated how to identify the longitude and latitude using the compass, leaving us in awe of the scientific advancements of that time. A helpful tip: make sure to visit during sunlight, as it enhances your understanding of how the clocks and other instruments function. It was an amazing and educational visit, absolutely worth experiencing for anyone interested in history, astronomy, and culture!
