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.
Nowadays, Kilkenny Castle is effectively three-sided. One of the four walls - and one of the great round drum towers - has disappeared over time.
Where did it go? Well, the Eastern wall and the North-Eastern tower were blown up during the 1650 Cromwellian siege of Ireland.
Collectively, Kilkenny people are known as 'The Cats', most specifically in the arena of hurling
The Butler family handed Kilkenny Castle over to the people of Kilkenny in 1967 – for £50!
