Continued from Jaipur: My first impressions.
“Jantar Mantar” meaning “instruments for measuring the harmony of the heavens” is situated right opposite the City Palace in Jaipur. Coming out of the gates of City Palace, I stopped at the ticket window to purchase the entry tickets to the observatory.
As I entered I found that the observatory complex is a large one, and has a collection of several (19 in all) architectural astronomical instruments that had been constructed in the early 18th century, with stone, marble and bronze. These devices were used to measure time and space, and for observing the astronomical positions of planets and stars. One of the instruments was the world’s biggest stone sundial, which gives the local time with an accuracy of 2 seconds.
Of particular interest to me were twelve instruments, known as Zodiacic Circles, which were used for measuring the latitude and longitude of celestial bodies. There are twelve such instruments corresponding to each zodiac sign.
