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.
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

"To understand Kilkenny's unique character one should retire from the busy streets to the lovely Castle Park and, standing within the shadow of the ancient pile, contemplate the great jumble of roof-tops, old and young, which tumble down to the quiet-flowing river beneath. Here dove-grey spires and battlemented towers proclaim a city old in Christian living and wise in human experience. One can feel the heartbeat of an ancient civilised community."
Katherine M Lanigan, Gerald Tyler, 'Kilkenny, Its Architecture & History', Appletree Press 1977
Kilkenny is 117 kilometres (73 mi) away the capital Dublin and 48 kilometres (30 mi) north from the nearest city Waterford. Wexford is 80 kilometres (50 mi) to the south-east and Limerick is 122 kilometres (76 mi) to the west.
The "Kilkenny Cats" nickname stems from the feral felines that once inhabited the Dunmore caves in the north of the county.
Kilkenny Castle has soared past some incredible competition to take the title of the most popular paid visitor attraction managed by the Office of Public Works (OPW) in Ireland.
