The Legend of Ha Long Bay: A Dragon’s Gift

“Ha Long” is “Descending Dragon,” which comes from an ancient legend about dragons. When Vietnam was under threat from foreign invaders, the Jade Emperor sent a family of dragons from heaven to defend the land and protect the Vietnamese people.

They began spitting out jewels and jade, which formed islands and islets, creating a natural fortress that halted the invaders’ advance. The location where the Mother Dragon landed was Halong Bay.

This enchanting legend still plays a key role in the cultural identity of the area, drawing tourists who are fascinated by its mystical origins.

Geological History: 500 Millions Years 

Scientists estimate that Ha Long Bay began forming around 500 million years ago, with its karst landscape shaped by tectonic activity, sea-level changes, and erosion. Rainwater and waves sculpted the limestone into towering cliffs, jagged rocks, and hidden caves, creating the bay’s distinctive topography of over 1,600 islands. Key geological events include the formation of a thick limestone layer during the Carboniferous and Permian periods (240 – 340 million years ago) and the Halong depression during the Neogene period (10 – 26 million years ago). The most intense erosion occurred in the Quaternary Pleistocene epoch, 11,000 to 2 million years ago.

Early Human Settlements: Traces of Ancient Civilizations

Ha Long Bay is not only rich in natural beauty but also in archaeological significance. Evidence of human activity in the area dates back as far as 18,000 years ago. Archaeologists have uncovered traces of early civilizations, including the Soi Nhu, Cai Beo, and Halong cultures, which once thrived in the region.

SOi Nhu Culture

This culture was centered in areas like Halong and Bai Tu Long, with key archaeological sites such as Mê Cung and Thiên Long. Excavations have uncovered remains of mountain and freshwater shellfish, along with simple stone tools. The Soi Nhu people primarily relied on fishing, shellfish gathering, and foraging for fruits, bulbs, and roots.

CAI BEO CULTURE

Located in Ha Long and Cat Ba Island, the inhabitants developed advanced sea-exploitation skills. They were ancient fishermen, and their fishing village was one of the largest ever found in Vietnam. The Cai Beo culture serves as a link between the earlier Soi Nhu culture and the later HaLong culture.

Ha Long Culture is one of four key prehistoric coastal cultures in Vietnam, along with Hoa Lộc (Thanh Hoá), Bàu Tró (Quảng Bình), and Xóm Cồn (Khánh Hoà).

Around 50 HaLong Culture relics have been found on the islands of Ha Long Bay, known for their distinctive stone tools and pottery. The people of this era likely developed watercraft to trade these items with other regions. Evidence of this includes Ha Long-style axes discovered not only in northern Vietnam but also in China.
