Hanumangarh is an agricultural town in northern Rajasthan near the Punjab border. It is best known for the Kalibangan archaeological site, one of the most important Indus Valley Civilization excavation sites in India, located about 30 km south of town. The ruins date back to around 3000 BCE and include evidence of the earliest known ploughed field in the world.
The town itself is not a conventional tourist destination, but history enthusiasts will find Kalibangan and the Bhatner Fort — one of the oldest forts in India, dating to the 3rd century, and the site of some of the subcontinent's most fought-over medieval battles — worth a detour.
