A site complex of mainland Southeast Asia in northern Laos with about 250 stone burial jars, up to three meters high, together with other megalithic monuments (menhirs) and pottery jar burials. The jars contained few remains as the bones appear to have been cremated. Artifacts on the burial and ceremonial sites include bronze and iron with local and possible Indian affinities. The sites appear to predate Hindu/Buddhist influence, c 300 BC-300 AD.
