Da Nang is a major port city in the South Central Coast of Viet Nam, on the coast of the South China Sea at the mouth of the Hàn River. It is the commercial and educational center of Central Viet Nam; its well-sheltered, easily accessible port and its location on the path of National Route 1A and the North-South Railway make it a hub for transportation. It is located within 100 km of several UNESCO World Heritage Sites, including the Imperial City of Hue, the Old Town of Hoi An, and the My Son ruins. The city was previously known as Cua Han during early Dai Viet settlement, and as Tourane (or Turon) during French colonial rule. Before 1997, the city was part of Quang Nam-Da Nang Province. On 1 January 1997, Da Nang was separated from Quang Nam province to become one of five independent (centrally-controlled) municipalities in Viet Nam. Da Nang is listed as a first class city, and has a higher urbanization ratio than any of Viet Nam's other provinces or centrally governed cities. In the 2009 census and base urban population, Da Nang was the 4th largest city in Viet Nam.
