Residents of Muong Co village in My Thanh commune, Lac Son district have been delighted to learn that the ancient rock carvings at the local Co stream were officially designated a provincial-level archaeological site.


A display of the newly designated provincial archaeological site of ancient rock carvings at Suoi Co, exhibited at the My Thanh People's Committee.

Emphasising the significance of the site, Bui Van Toi, Vice Chairman of the communal People’s Committee, said Muong Co is an ancient land with a long-standing history of human settlement. The central area of the site was once a dense forest, surrounded by rolling hills. The rock engravings were discovered during local agricultural activities.

Co stream stretches approximately six kilometres from Mount Voi through several hamlets – Chum, Ram, Co Giua, Vo Co, and Bui Ruong – before emptying into Canh Tang lake. Surveys and research in the area uncovered two engraved rock formations roughly 25 metres apart. A further granite boulder was later identified, partially buried in the ground.

Preliminary assessments by archaeologists suggest that the carvings date back to Vietnam’s prehistoric and early historic periods, approximately 2,000 years ago.

Among the three, one prominent hexagonal stone features a large carving with clearly defined incisions, including a stylised figure with an exaggerated belly, arms raised skyward. Above each arm are concentric circles with central dots – motifs characteristic of Dong Son bronze culture. The second rock features four distinct sets of similar carvings, while the third resembles a fish, marked by nine concave holes, referred to locally as the "doong stone."

According to local tradition, annual rituals are conducted at a small shrine located about 100 metres from the carved stones.

Dr Nguyen Viet, Director of the Centre for Southeast Asian Prehistory, said from an archaeological perspective, these rock carvings represent one of the rare traces of artistic and technical expression in the prehistoric–early historic era. They indicate a significant cognitive leap in how ancient communities in Hoa Binh’s heartland engaged with their natural surroundings by turning natural stone surfaces into artificial spaces.

Bui Thi Dien, head of the women’s union in Ram hamlet, added that like many here, she recognises the responsibility to preserve the site and protect its surroundings, maintaining their natural state.

Nguyen Thi Linh Ngoc, Deputy Director of the provincial Department of Culture, Sports and Tourism, noted that the site holds considerable value for research on Vietnam’sand even the world’s prehistory. She stressed the importance of ongoing preservation and called for expanded surveys to uncover further rock art in surrounding areas to ensure no ancient heritage is left undocumented.
