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.
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.
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.
The "Kilkenny Cats" nickname stems from the feral felines that once inhabited the Dunmore caves in the north of the county.
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.
The Butler family handed Kilkenny Castle over to the people of Kilkenny in 1967 – for £50!
