The Bihar archaeological directorate has found fragments of a few ancient sculptures from the ancient fort at Devangarh in Nawada district during the recent excavation.The Devangarh fort is perhaps the oldest in Bihar as the artefacts found there were from the Neolithic (from 3000 B.C. till 1500 B.C.) to the Gupta (4th-5th century AD) periods.The excavation site is spread over an area of 80 acres. The evidences of fort were first reported around 15 years ago by the then curator at Nawada museum, Awadh Kishor. Apart from identification of walls, three big statues have also been found — two related to Buddhism and one with Hinduism.
