Cork (/kɔːrk/; Irish: Corcaigh, pronounced [ˈkoɾkɪɟ], from corcach, meaning "marsh") is a university city in Ireland, located in the South-West of the island, in the province of Munster. Cork has a population of 125,622 and was founded during Viking invasions around 915.
The city is situated on the River Lee which splits into two channels at the western end and divide the city centre into islands. They reconverge at the eastern end where the quays and docks along the river banks lead outwards towards Lough Mahon and Cork Harbour, which is one of the largest natural harbours in the world by navigational area. The city's charter was granted by Prince John, as Lord of Ireland, in 1185. Cork city was once fully walled, and the remnants of the old medieval town centre can be found around South and North Main streets.
