Sơ sử Kông Chro: Giá trị di sản và giải pháp bảo tồn, phát huy giá trị – Prehistoric and protohistoric archaeology of Kông Chro: heritage values and strategies for conservation and promotion

Abstract

The system of opal stone axe workshops at H'lang (Yang Nam Commune, Kông Chro District, Gia Lai), together with recent archaeological discoveries, reveals a large-scale prehistoric lithic production center in the upper Ba River basin. These interconnected sites demonstrate a full chaîne opératoire—from raw material selection and fl aking to grinding and fi nal tool shaping. The technological uniformity and typological consistency of the artifacts indicate a high degree of specialization, refl ecting advanced labor organization and raw material exchange among ancient Central Highlands communities. New fi ndings, including unfi nished tools, production debris, and habitation traces, provide further evidence of a distinct inland lithic tradition in the central region. The H'lang workshop complex holds signifi cant value for understanding prehistoric cultural development and serves as a foundation for conservation planning, exhibition, and sustainable archaeological heritage promotion in Gia Lai and the broader Central Highlands.
