We report the archaeological findings from the historic site of Kuchchaveli in the northeastern coast of Sri Lanka, based on our excavations in 2011. The Kuchchaveli complex revealed features of a Mahāyāna Buddhist centre during the 7th and 8th centuries as indicated by the structures and an inscription as well as a number of Buddhist sculptures and carvings. Archaeological material and a radiocarbon date of 1880 ± 30 BP from a test pit indicate an earlier occupation as well. Our excavations offered insights to the structures built at Kuchchaveli and yielded pottery fragments, glass beads, faunal remains and other artefacts of interest. This report highlights findings from six test pits, where two test pits correspond to the possible bodhigara and water tank of the monastery. The similarity of the Kuchchaveli glass finds to those from other sites in Sri Lanka highlights the internal circulation of glass beads during the period that Kuchchaveli was an active site. The faunal remains suggest that a mix of domesticated and wild animals were part of the diet in the community. Apart from being a monastic establishment linked to the southeast coast of India, Kuchchaveli revealed trade activities with other regions over a long period, particularly in the Middle Historic Period of the region.
