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.
William the Earl Marshall (Strongbow's son-in-law) built the first stone castle on the site, which was completed in 1213. This was a square-shaped castle with towers at each corner; three of these original four towers survive to this day
The annals tell of a terrible massacre which took place in Dunmore Caves, with 1000 people killed by attacking Vikings in 928AD. Over the years there have been numerous finds of human bones, which together with finding of the Viking artifacts, seem to bear out that terrible tale.
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
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.
Gulliver's Travels author, Jonathan Swift, attended Kilkenny College in the late 17th century, and a building at the college was named after him in 2007. Swift's fellow students included playwright William Congreve and the philosopher George Berkeley – after whom California’s Berkeley College is named.
