The Hawaii Capital Historic District in Honolulu, Hawaii, has been the center of government ever since the earliest days of the unified Hawaiian Kingdom. Centered on Bishop Street and Fort Street Mall, the central business district is roughly bounded by Nuʻuanu Avenue, Nimitz Highway, Richards Street, and Vineyard Boulevard. This area contains most of the headquarters buildings of Hawaiʻi-based companies and most of the skyscrapers. Located between Nuʻuanu Stream and Nuʻuanu Avenue, Chinatown at one time was the center of Chinese cultural contact on the island. Central to this area is the open-air Oʻahu Market. The area around Nuʻuanu Avenue has become an ‎, thanks to the renovation of the Hawaiʻi Theatre. Honolulu Harbor, also called Kulolia and Ke Awa O Kou, is the principal seaport of Honolulu and the State of Hawaiʻi in the United States. It is from Honolulu Harbor, located on Mamala Bay, that the City & County of Honolulu was developed and urbanized, in an outward fashion, over the course of the modern history of the island of Oʻahu.
