The only completed Jantar Mantar in India

According to sources it is the only completed Jantar Mantar in India. According to me it is best place in Jaipur . . The place is completely scientific. Please take guide with you to understand completely as there are almost all instruments which cannot be understood without proper guidance. Must visit place.

This is the original Jantar Mantar. At the first look, its okay and I was just drifting but despite my aversion, I reluctantly hired a 'pestering' Guide. But, really, that must be one of the best thing I ever did. This 'pestering' Guide opened my eyes and my jaws and my senses and . No, not my pants . Okay . . This IS the MARVEL of INDIAN SCIENCE and TECHNOLOGY. Period.

Jantar- Mantar-A live proof of profound knowledge, expertise of Indian ancient scholars

Appreciate the accuracy of each and every clock, instrument built during the time when everything (almost) was done manually. Size, alignment, angles, measurements everything is perfect and it is no wonder that our ancestors were far ahead of their time and visionary to have this magnificent instruments built for generations to come. It will take us years today only to understand how these were built let alone build some thing new from scratch.Best places to take students on educational Tours.

Very Interesting Place

This is the most fascinating monument in the whole of north India. It is more fascinating than the Taj Mahal. I took a video guide which costs around 250. I spent almost 2 hours in the afternoon. Did not get bored one bit. The video guide will guide you through the different celestial structures. It is the first instance where a ruler of India has paid so much attention to science. In a country steeped in rituals and poverty, this monument is as refreshing as lemon juice.

Must be made famous

This place shows how intelligent people used to be in those days. This place is all about time, sun and its position which affects life of an individual. A place for astrology. How one can see time through position of sum.This place must be visited. The place will show which season is going on, what is the time, in which sun sign the sun is residing, what is the latitude at which the sun is. There is much more to understand.Literate people should visit the place and understand the concept behind it. It should be made popular among the students.

A humbling look at the work of an 18th century genius

I had never heard of this fascinating outdoor observatory before coming to Jaipur, but once there I found it hard to pull myself away (even though the sun was intense and the rest of my crew wanted to find shade! When you think of all the uses made over the years of inherited power and wealth, you usually think of vainglorious palaces, or wars, or fortresses (and of course those all can be found in Rajasthan as well) but seldom do you find such a magnificent realization of intellectual curiosity and a desire to understand the unknowable. The architectural structures of this celestial observatory are stunningly beautiful and poetic, their size is mindboggling, and the fact that they actually are accurate instruments of observation is amazing. Sawai Jai Singh was one of those rare visionaries who changed the world.

Nice loaction

There are plenty of observatories all over the world, but the Jantar Mantar is considered to be one of the largest observatories ever built. Combining religion, science and art, the Jantar Mantar is the name given to a series of five, magnificent structures built in Jaipur, New Delhi, Ujjan, Varanasi and Mathura. Jaipur was the seat of Maharaja Jai Singh II during the 1720's and this is when this magnificent structure was built here. The Jantar Mantar in Jaipur is considered to be the largest of the five observatories and also houses the world's largest sundial. The Universe and the Cosmos have always been of interest to man, and it was this interest that compelled the Maharaja to build an astronomical observatory. The term 'Jantar Mantar' is derived from the Sanskrit terms 'Yantra' and 'Mantra' meaning 'instruments' and 'formula' respectively. The term 'Yantra' was replaced with 'Jantar' which means 'magical'. The Jantar Mantar houses various architectural and astrological instruments that have caught the interests of astronomers, historians and architects around the world.

Measurement of time at different levels

One can see the how time was calculated in the olden days. Movement of planets at different times, scale for calculation of Solar & Lunar movement. It is better to have a guide who will explain in detail. Worth seeing place. One can have any number of photos/videos inside.
