A few years ago, the archaeological survey has discovered the ruins of an ancient monastery, at Adi Badri in Yamunanagar. In the travelogues of Chinese pilgrim Huang Tsang we find a mention of five monasteries with about thousand monks in the area around Shung, which is a village just a few miles away from this spot. Limited excavations done by archaeologists in a big mound in Shung area have revealed artifacts belonging to various periods ranging from 500 BC to 15th century AD. These include figurines of both Hindu deities and of the Buddha, his two prominent disciples and Bodhisatvas. Huan Tsang mentions that the Buddha and venerable Ananda had visited these monasteries in Shung and ordained many monks here. He saw four stupas built by Emperor Asoka – one to commemorate the Buddha’s visit to this place, another contained the hair and nails of the Buddha, and two more containing the hair and nails of the chief disciples of the Buddha, Sariputta and Mahamoggallana.
At Adi Badri numerous statutes of the Buddha, and terracota pieces dating to 1st-5th century have been found, and kept in a museum made near this site.. Few cells to accommodate a person, can also be seen in the excavations. A meditation cell which is partly below the ground level is also visible.
The whole area is reverberating with ancient Buddhist history dating back to the times of Lord Buddha
