Historical PlaceJantar Mantar in Jaipur was constructed between 1728 and 1734 by Maharaja Sawai Jai Singh II, the founder of Jaipur. It is one of the five observatories built by him across India (others are in Delhi, Ujjain, Varanasi, and Mathura).
The observatory contains 19 large-scale astronomical instruments, each designed for specific calculations such as:
1..Measuring local time
2..Determining the position of stars and planets
3..Calculating eclipses
4..Tracking zodiac signs
5..Measuring altitude and azimuth
The most famous instrument is the Samrat Yantra, the world’s largest stone sundial, which can measure time with an accuracy of about 2 seconds.
The monument represents the fusion of science, astronomy, mathematics, and architecture during medieval India. Due to its outstanding universal value, it was declared a UNESCO World Heritage Site in 2010.
Today, it stands as one of Jaipur’s top attractions and an important scientific heritage site.
