Located in the Hunsgi and Baichbal valleys of peninsular India, Isampur is a remote village in Shorapur taluk of Gulbarga District. The quarry site at the village is the oldest known Stone Age site in India, which is dated over a million years. Isampur is one among the Acheulian sites of the Lower Paleolithic stage and records an early appearance of hominids in India. Excavations at this place have revealed that early humans exploited the stone resources in this quarry to make tools. The archeologists have found Acheulian assemblages, including a high density of chipped stone waste, bifacial tools, and hammer stones.
