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.
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.
Kilkenny, an inland county, is bordered by counties Wexford, Carlow, Laois, Waterford, and Tipperary. Geologically speaking it is mostly limestone, with areas of black marble around Kilkenny city. The rivers Nore, Suir, and Barrow flow through it.
In 1922, the Butler family - namely Lord and Lady Ossory - were residents of the castle. The Irish Civil war, raged around them. Lord Ossory memorably wrote that he was woken at the "unreasonable hour of 5.30am" by his butler, who brought the news that Republican forces had seized and occupied his castle.
All-time top scorer in the All-Ireland Senior Hurling Championship is TJ REID with 641 points in 82 games, scoring 30-551.
The Butler family handed Kilkenny Castle over to the people of Kilkenny in 1967 – for £50!
