[2][3] The Angkor Borei site was likely an early capital and a region where southeast Asian culture and arts fused in the ancient times.

[4] Archaeological excavations have yielded items that are carbon dated to roughly 1523 BC and thereafter, many related to early Buddhism and Hinduism, confirming a continuous human settlement at least for some 500 years.

Research has uncovered brick architecture, post holes for a large wooden structure, and a temple containing two Vishnu statues.

[6] Artifacts include ceramics, brick fragments, animal bone, vessels, clay pellets, slag, and stone statues.

[6] Vat Komnou cemetery is also a notable feature which was excavated and found to contain roughly 60 bodies ranging from 200 BC - AD 400.

[7] Males were found to be more than twice as common as females, many of which had stress fractures in their lower backs suggesting some sort of heavy labor.

It is notable for the oldest surviving temples, Khmer and Sanskrit inscriptions as a source, as well as perhaps the earliest Cambodian stone statues, based on the epigraphical evidence, iconography, and style, in Cambodia.

[9][3] Among these is the Triad of Phnom Da, a stone statue set of Vishnu and two of his avatars – Rama and Balarama (related to Krishna).
