The museum was established in 1956 by the ASI and preserved sculptures from Bodhgaya and from nearby villages. Within the walls of the museum compound, the Bodhgaya stone railing has been reconstructed. The museum also consists of a large collection of Pala period sculptures (9th-12th centuries) carved in black stone.
The site of Sarnath is identified as the place where Gautama Buddha delivered his first sermon. The excavated site has foundations of monastic dwellings, temples, and stupas. The collection covers structures within the excavated site. Excavations at Sarnath reveal that the oldest levels date to the Marurya period to the reign of Ashoka. The site contains the famous lion-capital memorial pillar from 3rd century BCE along with stupas from Gupta and Pala periods.
