About Munster

Munster is one of the four traditional Irish provinces, located in the south of Ireland. It is the largest of Ireland’s provinces by land area, and the third largest by population. The province is composed of six counties: Clare, Cork, Kerry, Limerick, Tipperary, Waterford.

Munster is the largest of Ireland’s four provinces by land area, and the third largest by population.

In early Ireland, the Kingdom of Munster was one of the kingdoms of Gaelic Ireland ruled by a “king of over-kings.” Following the Norman invasion of Ireland, the ancient kingdoms were shired into counties for administrative and judicial purposes. In later centuries, local government legislation has seen further sub-division of the historic counties.

Several sports in Munster are organized on a provincial basis, or operate competitions along provincial lines. This includes traditionally popular sports such as hurling, Gaelic football, rugby union and soccer, as well as cricket and hockey.

Munster is noted for its tradition of hurling. Three of the four most successful teams in the All-Ireland Senior Hurling Championship are from Munster; Cork GAA, Tipperary GAA and Limerick GAA. The final of the Munster Senior Hurling Championship is one of the most important days in the Irish GAA calendar. Munster is the only province in Ireland wherein every one of its counties has won an All-Ireland Senior Hurling Championship.
