A brief history of County Kilkenny

Kilkenny is located in the southeast of Ireland in the province of Leinster. The county of Kilkenny has three major rivers running through it, known as the Three Sisters: the Nore, the Suir, and the Barrow. In 1641 Kilkenny was actually the capital city of Ireland and remained the capital for nine years until Oliver Cromwell led the conquest of Ireland in 1649.

Kilkenny is known as the Marble City because of its distinctive black marble. The city has a medieval feel with well-maintained and preserved old buildings. Kilkenny is also home to one of Ireland's premier comedy festivals, the Kilkenny "Cat Laughs" festival.
