Jantar Mantar, Jaipur-Largest Astronomical Observatory

#Monument in Jaipur

The Jantar Mantar in Jaipur is an astronomical observation site built in the early 18th century. The Jantar Mantar is the largest of the five such magnificent observatories built in India. It was built by Maharaj Jai Singh II in the 1720s who himself was a great scholar in Astronomy. It was used to measure the distances and positions of celestial objects. The Jantar Mantar of Jaipur houses the world's largest sundial called the 'Samrat Yantra'.

The Jantar Mantar monument consists of 19 large instruments each serving a very specific purpose. It also contains fourteen geometric devices to measure time and track celestial bodies and also observe the planets around the sun. This is the most significant, most comprehensive, and the best preserved of India's historic observatories. It is an expression of the astronomical skills and cosmological concepts of the court of a scholarly prince at the end of the Mughal period. The Jantar Mantar entry fees are INR 50 for Indians and INR 200 for foreign travelers.

"I am weak in science and physics and in geometric and surely this place was not for me. But then this was on the trip menu and so we were here. Its a quite place in the midst of the city and obviously it had less visitors. People love taking their own pictures with the unusually ancient shaped objects. There are tabloids in front of every object which explain the usability of the object and if you can understand the technical terms then you might enjoy. Its a stunning park and basically no place to rest. You wouldn't want to stay long in summers as there is lack of shady places. Still I would say it can be visited for the sake of visiting. If you are physics, geometric and science freak then this is a place for you to discover what was there thousands of years ago. It really is fascinating to know how people would calculate the distance between the stars and planets with these simple instruments and that too simply being on earth. I would say its beyond imagination."

"Preview to India's astronomical capabilities from the past. A collection of architectural instrumentation... surprised to see a giant stone clock capable of measuring time accurately. There are almost 20 types of such instruments. Need a guide to understand at lest some of them."

"A fantastic place to be. The structures still depict the time and you can cross verify yourself(they give the jaipur local time so you have to add 27 minutes to get the ist as ist is based on allahabad standard time). The descriptions are detailed and there is even a show which runs there every 15 minutes which tells you through video about the place, the instruments and rest all. Photography is freely permitted and if you a science lover by any chance, you'll be spending hours here. The place mind you closes by 4:30 so its best recommended to go in the morning here before going to city palace as later it can get very hot here. "

""combination of science ,art and religion"----- this observatory was built by ruler swai jai singh ,he was a great scholar and agreat astrologer so he constructed this observatory , janrat mantar is one of the best observatory , near about more than 280 years old ,its really a combination of science and architecture, Still the astrologers used observatory device and instruments to calculate the auspicious date of wedding,by these devices in ancient time they calculate the accurate time , seasons and astronomy if you are visiting this place so please hired a government approved guide only,without guide you will not understand these observatory instruments and devices , there is not much explanation written on the board of the observatory Visited may 2016"
