Cork is the second largest city in Ireland and the island of Ireland's third most populous city. It is the principal city and administrative centre of County Cork and the largest city in the province of Munster. Cork had a population of 119,418 in 2011, while the addition of the suburban areas contained in the county brings the total of the urban area to 198,582. Metropolitan Cork has a population of 399,216, while the Greater Cork area is about 518,128.
County Cork has earned the nickname of "the Rebel County", while Corkonians often refer to the city as the "real capital of Ireland", and themselves as the "Rebels". The city is built on the River Lee which divides into two channels at the western end of the city. The city centre is located on the island created by the channels. At the eastern end of the city centre they converge; and the Lee flows around Lough Mahon to Cork Harbour, one of the world's largest natural harbours.
The city is a major Irish seaport; there are quays and docks along the banks of the Lee on the city's east side.
