The history of Dong Hoi is rooted in deep antiquity, long before the emergence of modern administrative boundaries. For centuries, this territory has served as a crossroads of civilisations and a vital strategic point on the map of Vietnam.
Foundation and Ancient Traces
Although Dong Hoi received its modern administrative city status relatively recently, people settled these lands thousands of years ago. Archaeological data allows us to distinguish several stages of early history:
- Bau Tro Culture: Traces of a Neolithic culture (approximately 5,000 years old) have been discovered in the city's vicinity. Archaeological finds, including pottery and stone axes, testify that ancient people actively settled the coastal zone.
- Champa Period: For a long time, the region was under the influence of the Champa Kingdom, and later became a zone of active interaction and territorial disputes during the southward expansion of the Vietnamese state.
Key Factors of Formation
The transformation of scattered settlements into a fortified city was dictated primarily by military-political necessity and geography:
- Strategic Defence: In the 17th century, during the era of confrontation between the Trinh and Nguyen feudal lords, this area became a critically important frontier. The famous strategist Dao Duy Tu erected the Luy Thay defensive wall system here, turning the district into an impregnable outpost.
- Geography: The city grew at the estuary of the Nhat Le River. This position ensured control over waterways and access to the South China Sea, which was vital for both the navy and maritime trade.
- Construction of the Citadel: In the early 19th century, under the Nguyen Dynasty, the brick Dong Hoi Citadel was built, definitively cementing the city's status as the administrative and military centre of Quang Binh Province.
Early Culture and Economy
The economy of early Dong Hoi was inextricably linked to the sea. Local residents traditionally engaged in fishing and seafood production. Thanks to its location on the main land route connecting the north and south of the country (the Mandarin Road), the city also developed as a trading hub where goods and cultural traditions were exchanged between various regions of Vietnam.
