Churu is a town in the desert region of Rajasthan state of India. It is the administrative headquarters of Churu District. It lies in the Thar Desert on the National Highway-65 connecting Pali to Ambala and is a junction station on the railway line to Bikaner. It is near the shifting sand dunes of the Thar Desert and has grand havelis with marvelous fresco paintings, namely Kanhaiya lal Bagla ki Haweli and Surana Haweli, with hundreds of small windows. It also has some fine Chhatris. Near the town is a religious seat of the Nath sect of Sadhus where there are life-size Marble statue of their deities and a place for prayers. There stands a Dharam Stup, a symbol of religious equality. At the centre of the town is a fort built about 400 years ago.
The economy of the town and surrounding area is mainly based on agriculture and animal husbandry. The oilseeds, especially mustard seed, is the predominant crop in recently developed small, well-irrigated fields. Wheat, kharif pulses, bajra (pearl millet), and gwar are other produces.
The region boasts record temperatures ranging from below freezing point in the winters to over 50 degrees in the summer afternoons. Before dawn in the months of December/ January one may not be surprised to notice ice in small waterpots or frozen water dews on the little vegetation. Yet one may find that summer nights are cooler and winter days are warmer. The variation in the minimum and maximum temperature is perhaps greatest for any place in the world. Perhaps it is the only place in the world where temperature dips below sub-zero but does not have snowfall.
