Ujjain, often referred to as the astronomical capital of India, has been an important center for science, astrology, and spirituality since ancient times. The Jantar Mantar or Vedh Shala of Ujjain is not only a historical site but also a remarkable achievement of Indian astronomy.
In ancient India, Ujjain was considered the base point for time calculation and calendar-making. The reason was its location on the Prime Meridian of India (Zero Longitude line). Just like Greenwich in London is taken as the global reference for time today, Ujjain was once known as the Greenwich of India.

Even today, this observatory reminds us that centuries before the rise of modern science in the West, Indian scholars and astronomers were already mastering complex astronomical studies and time calculations.
History
The Jantar Mantar of Ujjain was built by Maharaja Sawai Jai Singh II of Jaipur (1688–1743). Apart from being a great ruler, Jai Singh was deeply interested in mathematics and astronomy.
During his time, inconsistencies in Panchang (Hindu calendar) and astronomical calculations had increased. Different scholars provided varying times for eclipses, seasons, and religious rituals, which often created confusion. To resolve this issue, Jai Singh decided to build observatories equipped with instruments that could measure planetary movements and time with precision.
He established five observatories across India at:
- Delhi
- Jaipur
- Varanasi
- Mathura
- Ujjain
Among these, the Ujjain observatory was considered the most significant because of the city’s historical role as the center of time calculation. The construction was completed around 1725 AD.
Jai Singh named it “Vedh Shala” since its purpose was to connect astronomical principles mentioned in the Vedas with practical observation and make them useful for society in determining calendars, eclipses, and ritual timings.
