Dong Son village in the context of Mã River

Cổ Loa Citadel (Vietnamese: Thành Cổ Loa) is an important fortified settlement and archaeological site in present-day Hanoi's Đông Anh District, roughly 17 kilometers north of present-day Hanoi, in the upper plain north of the Red River. Various relics of the Bronze Age Phùng Nguyên culture and Đông Sơn culture have been found in Cổ Loa, although it was later established as the capital of Âu Lạc Kingdom during the 3rd century BCE (about 257 BCE). It might be the first political center of the Vietnamese civilization. The settlement’s concentric walls resemble a snail’s shell; it had an outer embankment covering 600 hectares.

The Dong Son culture, Dongsonian culture, or the Lạc Việt culture (named for modern village Đông Sơn, a village in Thanh Hóa, Vietnam) was a Bronze Age culture in ancient Vietnam centred at the Red River Valley of northern Vietnam from 1000 BC until the first century AD. Vietnamese historians attribute the culture to the states of Văn Lang and Âu Lạc. Its influence spread to other parts of Southeast Asia, including Maritime Southeast Asia, from about 1000 BC to 1 BC.

The Đông Sơn people were skilled at cultivating rice, keeping water buffalos and pigs, fishing and sailing in long dugout canoes. They also were skilled bronze casters, which is evidenced by the Dong Son drum found widely throughout northern Vietnam and Guangxi in China.
