Ānbāng

An Bang was a northeastern frontier region of Đại Việt, encompassing a coast of wooded hills, islands and sheltered waters. Its position connected the Red River delta with the routes towards southern China. In 1466 the Lê court established An Bang as an administrative region. The name later became An Quảng, while the coast and its island ports continued to mark the kingdom's northeastern maritime approaches.

The later city of Hạ Long lies here.
