The announcement coincided with the opening of a public exhibition at the Hanoi Museum showcasing discoveries from the site, which spans multiple periods from the Phung Nguyen (c. 2,000–1,500 BC), Dong Dau (c. 1,500–1,000 BC), and Go Mun (c. 1,100–800 BC) cultures through the Dong Son (800 BC–100 AD) and Late Dong Son eras.

Archaeological excavations at Vuon Chuoi, first discovered in 1969, have covered more than 7,500 square meters in 11 campaigns conducted by the Hanoi Department of Culture and Sports and partner institutions.

A major excavation from March 2024 to March 2025 revealed residential areas, workshops, burial sites, and artifacts dating to the Early Dong Son period, around 3,500 years ago.

Among the finds were rare jade axes, interpreted as symbols of leadership, and jewelry shaped like phoenix heads, reflecting the social hierarchy of the village. 

Nearly 1,000 artifacts, documents, images, and maps are on display in the museum, accompanied by 3D projections and short films reconstructing daily life in the ancient settlement.

The exhibition also honors local residents and researchers from Lai Xa Village who contributed to preserving and studying the site.

It also coincides with the release of a book documenting the 2024–25 excavations.
