Ujjain served as India’s prime meridian for centuries, helping astronomers calculate longitude and celestial events long before Greenwich was established.
The Ujjain observatory, built by Maharaja Sawai Jai Singh II in the 18th century, served as a hub for astronomical calculations and calendar-making. Instruments similar to those at Jaipur allowed tracking of celestial bodies, eclipses, and planetary motion. Ujjain was historically considered India’s meridian reference, central to determining longitude and astrological timings. The observatory’s large-scale instruments, including quadrants and gnomons, permitted accurate measurements without telescopes. Unlike modern observatories, the architecture itself served as the scientific tool. Knowledge from Ujjain influenced calendars, astrology, and even religious ceremonies across India. The site reflects an intersection of empirical observation, social governance, and spiritual practice. Scholars continue to study its instruments to reconstruct 18th-century astronomical techniques.
