Da Nang

Da Nang is a major port city in the South Central Coast of Vietnam, on the coast of the South China Sea. It is one of the five independent municipalities in Vietnam.
It was called Tourane or Turon during the French colonization of Vietnam.

History
According to Hỏi đáp về Quảng Da Nang's name originated from the Cham word Da Nak, meaning "opening of a big river".

In 1847, French vessels dispatched by Admiral Cécille bombarded Đà Nẵng in response to persecution of Roman Catholic missionaries.

In August 1858, French troops landed under the orders of Napoleon III, beginning colonial occupation in the area. As a concession, it was renamed Tourane in French. It came to be considered one of Indochina’s five major cities. During the Vietnam War, the city was home to a major air base that was used by both the South Vietnamese and United States air forces. The population has since increased to over 1 million inhabitants. Refugees from the city of Huế have contributed to the rise since the aftermath of Hue in 1968.
