A Living Observatory in the Heart of India
Ujjain is home to Vedhshala, India’s only working Jantar Mantar. While other observatories built by Raja Jai Singh in Jaipur, Delhi, Varanasi, and Mathura stand mostly as historical monuments, Vedhshala in Ujjain is still actively used for astronomical research and weather forecasting.
Why is Ujjain So Important in Astronomy?
Ujjain has held a key position in Indian astronomy for centuries. Ancient texts like the Surya Siddhanta and Panch Siddhanta were composed here, making Ujjain a center of celestial knowledge. Historically, Ujjain was considered the Greenwich of India, serving as the first meridian of longitude for Hindu geographers.
Interestingly, Indian astronomers believed the Tropic of Cancer passes through Ujjain. This made the city a significant point for astronomical calculations in ancient times.
Raja Jai Singh and the Construction of Vedhshala
The current observatory was built in the 18th century by Maharaja Jai Singh II (1686–1743), a scholar and ruler with deep interest in mathematics and astronomy. He translated the works of Ptolemy and Euclid into Sanskrit from Arabic sources and created five observatories across India.
Among all these, Ujjain’s Vedhshala remains the only one in active use. It is operated by the Department of Education and plays a role in preparing the annual ephemeris—a chart that tracks the movements of celestial bodies.

- Telescope: For viewing the moon, Mars, Jupiter, and their moons.
- Planetarium: A small setup helps visitors understand the basics of space and planetary motion.
- Weather Station: Used for forecasting based on traditional and modern systems.
