County Cork (Contae Chorcaí in Irish) is the most southwesterly and the largest of the modern counties of Ireland. The city of Cork is the third largest city after Dublin and Belfast. Cork city takes its name from the marshy land on the banks of the River Lee - the Irish form of its name means marsh - on which St. Finbarr founded a monastery around AD 650. The city's narrow alleys, waterways and Georgian architecture give it a distinctly Continental feel.

Often called "The Rebel County", the region is so named because it has often taken a position in major conflicts contrary to that of most of Ireland.

The remote western area of the county, known as West Cork, is a popular destination for tourists, who visit the small villages and islands including Sherkin Island, Clear Island and Dursey Island. Mizen Head, the "southwesternmost point in Ireland" is also in West Cork, as is Sheep's Head. West Cork is noted for its rugged natural beauty, fine beaches and distinct social atmosphere, which is more relaxed than most of the country.
