Hanumangarh was the kingdom of ‘Bhatti’ Rajputs and hence its earlier name was ‘Bhatner’. Later it was named as ‘Shardulgarh’ when Raja Shardul Singh won it. Since it was won on Tuesday, which is the ominous day for monkey-god Hanuman, it was rechristened as ‘Hanumangarh’ – the Fort of Hanuman Monkey-god. A 900 year old ‘Bhatner’ fort is situated in the middle of ‘Hanumangarh Town‘. The description of which can be found in ‘Aaine-Akbari‘. A famous ‘Bhadrakali temple’ is situated near the town on the banks of Ghaggar river.
The area around Hanumangarh appears to be quite old. It has yielded a number of terracotta decorative tiles in the late Kushana style along with a number of coins. Two terracotta capitals at the depth of 15′ from the top of the mound with stepped pyramids along their edges have been discovered.
