Gwangju [a] (Korean: [kwaŋ.dʑu] ⓘ) is South Korea 's sixth-largest metropolis. It is a designated metropolitan city under the direct control of the central government's Home Minister. The city was also the capital of South Jeolla Province until the provincial office moved to the southern village of Namak in Muan County in 2005 because Gwangju was promoted to a metropolitan city and was independent of South Jeolla province.
