Archaeologists have unearthed artefacts believed to be 2,300-year-old while carrying out excavation at the Asurgarh Fort in Odisha’s Kalahandi district.A nine member team of Archaeological Survey of India led by Dibishada B. Garnayak, Superintending Archaeologist, Excavation Branch-IV, Bhubaneswar, excavated the items dating from Mauryan to Kushan period.“The present archaeological work reveals a number of brick structures. Wedge shaped bricks are also noticed in the circular structures. Most of the structures have terracotta tiles with groves and hole for socketing,” said Mr. Garnayak.“The Asurgarh people during that time probably used stone rubbles and tile fragments for flooring their houses and the streets. Besides, silver punch marked coins, silver and copper toe ring and ear rings, beads of carnelian, jasper, beryl, garnet, agate and coral have been found,” he said, adding that some of the artefacts were as old as 2,300 year.Glass banglesOther discovered artefacts include, glass bangle pieces of different designs and colours, sling balls, pestle, iron equipment like small wheel, ring, and arrow head.“The findings of coral beads and imperial variety of silver punch mark coins strongly indicates about long distant trade and association of hinterland people with seafaring people,” pointed out Mr. Garnayak.It is believed that the fort is surrounded by moat on its northern, eastern and southern sides. “Close to the western rampart, the river Sandul flows to the north thereby forming a natural moat on the western side of the fort. On the eastern side of the fort there is an extensive lake. The fort had four wide gates in four cardinal directions and at each gate was installed one guardian deity. These guardian deities are named as Ganga at the eastern gate, Kalapat at the western, Vaishnavi at the northern and Dokri at the southern gate,” he said.
