The Butler family handed Kilkenny Castle over to the people of Kilkenny in 1967 – for £50!
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
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.
St Canice's Cathedral, also known as Kilkenny Cathedral, present building dates from the 13th century and is the second longest cathedral in Ireland. The Cathedral is named after Saint Canice, who also gave his name to the city.
The population of County Kilkenny is 95,419 according to the 2011 census ... plus an undisclosed number of Kilkenny cats.
