Kilkenny Castle was founded in Medieval times, but its most significant moments have been played out during more recent history. The castle was featured in Oliver Cromwell's re-conquest of Ireland in 1650; and was besieged during the Irish Civil War in 1922.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 CorkFilm star George Clooney’s great-great-grandfather was baptised Nicholas Clooney in Windgap church, Kilkenny, on July 23, 1829.
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.
Gulliver's Travels author, Jonathan Swift, attended Kilkenny College in the late 17th century, and a building at the college was named after him in 2007. Swift's fellow students included playwright William Congreve and the philosopher George Berkeley – after whom California’s Berkeley College is named.
