Accra is the capital and largest city of Ghana, covering an area of 225.67 km2 (87.13 sq mi) with an estimated urban population of 2.27 million as of 2012. It is organized into 10 local government districts – 9 municipal districts and the Accra Metropolitan District, which is the only district within the capital to be granted city status. "Accra" usually refers to the Accra Metropolitan Area, which serves as the capital of Ghana, while the district within the jurisdiction of the Accra Metropolitan Assembly is distinguished from the rest of the capital as the "City of Accra". In common usage, however, the terms "Accra" and "City of Accra" are used interchangeably.

Formed from the merger of distinct settlements around British Fort James, Dutch Fort Crêvecoeur (Ussher Fort), and Danish Fort Christiansborg as Jamestown, Usshertown, and Christiansborg respectively, Accra served as the capital of the British Gold Coast between 1877 and 1957 and has since transitioned into a modern metropolis.
