Kotla Nihang Khan is also a major archeological site associated with the Bronze AgeIndus Valley civilization, dating to the 3300-1300 BCE period. Several underground structures, including a furnace dating to the Bronze Age, were unearthed here.[2] Kotla Nihang Khan's initial settlement has been dated to 2200 BCE based on analysis of excavated artifacts.[3] The excavated area here shows two distinct sectors: an eastern sector where pottery remains are indicative of Urban Harappan Culture, and a western sector where Urban Harappan artifacts are found mixed with Bara Ware. This is believed to indicate coexistence or a transition between the original Harappan inhabitants and the later Baran settlers at the settlement.[4]
Gurdwara Bhatha Sahib
This place is famous for a historical Gurdwara Bhatha Sahib. Guru Gobind Singh, the tenth Guru of the Sikhs, visited this place in 1688 during their return from Anandpur Sahib and stayed there where there was a brick kilan known as a Bhatha in vernacular Punjabi language. Later, the Gurdwara was built in memory of the visit of the Guru which came to be known as Bhatha Sahib.
There is a fort in the village known as Kotla Nihang Khan Fort which was built by the then Afghan Zimindar ruler Nihang Khan who ruled over 80 villages in the 17 Century.
