Maharaja of Amber (modern-day Rajasthan), Sawai Jai Singh II, established five astronomical observatories in his native territory between 1724 and 1727. Owing to his passion for mathematics and astronomy, Jai Singh adapted and added to the designs of earlier sight-based observatories to establish a unique structure for astronomical measurement.

Jantar Mantar, also known as Vedh Shala, consists of 13 architectural astronomy instruments and was built in the year 1725, in Ujjain. The name Jantar Mantar comes from two words-'Yantra' and 'Mantra', which together mean 'a calculation instrument'. The primary purpose behind the construction of Jantar Mantar was to illustrate and compile the data collected by astronomical calculations, the results of which have helped in the study of the movements of the sun, planets and their moons.

BTW did you know? Before Greenwich was accepted as the prime meridian universally, Ujjain was considered as the central meridian for time in India. Ujjain, situated at a distance of 56 km from Indore, is geographically placed at the precise spot where zero meridian of longitude and the Tropic of Cancer meet, which is why it is known as the 'Greenwich of India'. One can see the location of Ujjain pinpointed on the Tropic of Cancer, on a large globe outside Jantar Mantar.

The observatory houses a hybrid planetarium with a 12-metre dome and 125 seats, on its premise. Famously known as Taramandal, this planetarium showcases 20 and 30-minute shows on planets, stars, constellations and galaxies! The programmes are available at an interval of 30 minutes for a minimum of 10 people at least. One has to buy the tickets for the show from the ticket counter separately, as it is not included in the entry fee.
