Kilkenny.As of 2011, Kilkenny had played a total of 371 championship games, winning 265, drawing 16 and losing 90. They had played Dublin the most times(82) .
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.
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 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
