The "Kilkenny Cats" nickname stems from the feral felines that once inhabited the Dunmore caves in the north of the county.
In 1650 invading Cromwellian forces mounted an attack on Kilkenny castle and although it was initially successfully defended they eventually managed to take control of the city by another route.The gravestone of Daniel O’Connell in Glasnevin Cemetery, Dublin is made from Kilkenny black marble, and the stone was also used in the construction of Cobh Cathedral in Cork
The elevation of Kilkenny is 60 metres (200 ft) above sea level. The area of Kilkenny borough is 3.74 square kilometres (1.44 sq mi). Kilkenny is the smallest city in Ireland and although all cities in Ireland are by the coast or along a river Kilkenny is the only city that is not tidal.
Kilkenny Castle was founded in Medieval times, but its most significant moments have been played out during more recent history. The castle was featured in Oliver Cromwell's re-conquest of Ireland in 1650; and was besieged during the Irish Civil War in 1922.
The Butler family handed Kilkenny Castle over to the people of Kilkenny in 1967 – for £50!
