Ujjain is the quiet and relatively small provincial town. Ujjain is situated about 60 kms. from Indore. Ujjain is one of the greatest cities of ancient India and one of the seven sacred cities of Hindus in India. It is also one of the four towns where the Kumbh Mela is held and plays as a host up to a million pilgrims who gather on the place every twelve years. Various people came here to bath in the Shipra river and worship at the temples on its banks. According to Hindu astronomers, it is also the city from where the Tropic of Cancer pass. This explains the presence of the observatory (Vedha Shala) built by the Raja Jai Singh of Jaipur in 1725. Even today, the Ephemeris tables (predicted positions of the planets) are published here. Ujjain is also known for industry and crafts. The best season to visit Ujjain is from October to March.
