The Butler family handed Kilkenny Castle over to the people of Kilkenny in 1967 – for £50!
Irish legend describes Dunmore Cave, seven miles north of Kilkenny, as one of Ireland’s darkest places and the site where the monster Luchtigen 'The Lord of the Mice' was killed.
One of the most instantly recognised buildings in Ireland, Kilkenny Castle has been an important site since Strongbow constructed the first castle, probably a wooden structure, in the 12th century.
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.
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.
The "Kilkenny Cats" nickname stems from the feral felines that once inhabited the Dunmore caves in the north of the county.
