The tangible cultural heritage along the Cau River.

The Cau River continues to flow through Hiep Hoa, Viet Yen, and Yen Dung districts (of Bac Giang province) and Yen Phong, Bac Ninh city, and Que Vo (of Bac Ninh province) before emptying into the Luc Dau River. For a time, the Cau River was a vital trade artery, making Bac Ninh, especially the Cau River basin, an early center of ancient Vietnamese civilization. Throughout thousands of years of history, a rich and unique tangible and intangible cultural heritage has flourished along the Cau River.

Most villages along the Cau River today have a very early history. In the Cau River basin, within Yen Phong district, many relics containing traces of ancient Vietnamese people have been discovered. At the Noi Gam site in Phu Cam village (Dung Liet commune, Yen Phong district), many artifacts from an on-site stone carving workshop have been found. Based on the crafting techniques and types of artifacts, the Noi Gam site belongs to the Dong Dau culture – a pre-Dong Son culture, especially the discovery of weights – evidence of economic exchange and trade in the Cau River region during the Bronze Age. The upper layer of the Noi Gam site contains pottery fragments from subsequent periods, many celadon potterys from the Ly, Tran, and Le dynasties...

The relics and artifacts of the villages along the Cau River are tangible cultural landmarks that bear witness to the continuous existence and development of the local inhabitants. These are unique works of art, showcasing the talent of successive generations throughout the thousand-year history of the nation, creating a rich and distinctive cultural heritage of the Cau River region. The people of the Cau River are proud of their ancestors' achievements and work together to preserve, protect, and promote the value of this heritage, contributing to the building of an advanced Vietnamese culture imbued with national identity.
