Bairat was a part of the Mauryan Empire. The ruins of the "Bijak-ki-pahadi" (Bairat Temple), a Buddhist Chaitya (chapel) from the 3rd century BCE located in Bairat, are the oldest free-standing Buddhist structures in India. The town is also home to ruins of a Buddhist monastery, a wood and timber shrine, and two rock-cut edicts (Bairat Edict and Bhabru Edict) from Emperor Ashoka; these date from the Mauryan period (circa 250 BCE). However, Akhnoor, a town in the union territory of Jammu and Kashmir is also considered by many as the ancient Virat Nagar.
