Cork is a city in Ireland, located in the South-West Region, in the province of Munster. It has a population of 125,622 and is the second largest city in the state and the third most populous on the island of Ireland. The greater Metropolitan Cork area has a population exceeding 300,000. In 2005, the city was selected as the European Capital of Culture. The city is built on the River Lee which splits into two channels at the western end of the city; the city centre is divided by these channels. They reconverge at the eastern end where the quays and docks along the river banks lead outwards towards Lough Mahon and Cork Harbour, one of the world's largest natural harbours.
