Experts also discovered traces of the ritual of incisor extraction in adults, which was common during the late Phung Nguyen culture 3,500 years ago, and a custom with social and spiritual significance. Craft production of jade, wooden, ceramic, and bronze objects reached a high level of specialisation. The jade-working area was arranged separately at the village entrance, possibly linked to ritual spaces.
This year, over 15,000 artefacts made of stone, bronze, ceramics, wood, bone, and iron have been recovered, along with tens of thousands of tonnes of ceramic fragments and soil containing plant remains. Among these, three groups of rare artefacts stand out. The items include green jade axes, the symbol of a leader’s power, discovered in a Pre-Dong Son burial, dating back approximately 3,500 years. Also recovered were phoenix-headed ornaments, reflecting the belief in totemic worship, and a collection of jade objects, including bracelets, earrings, beads, and tooth-shaped pendants, representing the elite class of ancient society.
These discoveries provide valuable documentary evidence, affirming the special historical and cultural significance of the Vuon Chuoi site in the development of the Metal Age in northern Vietnam.
Recognising its outstanding historical and cultural values, the Hanoi People’s Committee issued Decision No. 3134/QD-UBND dated June 23, 2025, officially designating the Vuon Chuoi Archaeological Site as a city-level relic site.
