The term Bavikonda in Telugu language means a hill of wells. As per its name, Bavikonda is a hill which has wells for the collection of rainwater. Bavikonda is located 15 km from the town of Visakhapatnam in Andhra Pradesh, India and is an immensely significant Buddhist site.
Excavation carried out in 1982-87 revealed an entire Buddhist establishment comprising a Mahachaitya, embedded with relic caskets, large vihara complex, numerous votive stupas, a stone pillared congregation hall, rectangular halls, a refectory etc. Artifacts discovered from the site include Roman and Satavahana coins and pottery dating back to the 3rd century BC to the 2nd century AD. A significant finding here is a piece of bone stored in an urn. This bone is widely supposed to be the mortal remains of the Buddha. In the urn, there is also a large quantity of ash.
The Bavikonda site, today, is counted amongst one of the oldest and immensely sacred Buddhist sites in the Asia. The ruins of the site stand reminder to the great Buddhist civilization that once existed in the southern part of India.
