Kilkenny Castle
Location: Kilkenny City, County Kilkenny
Originally a medieval wooden fortress built under Norman knight Strongbow—namesake of the famous cider—< strong>Kilkenny Castle served as the Butler family’s primary Irish seat. The Butlers trace their lineage to Theobald FitzWalter, Ireland’s inaugural Chief Butler, a title derived from the French Le Boitiler, overseer of King Henry II’s wine cellars. This role brought wealth from wine import duties. Notably, in the 1960s, the castle sold for a mere £50 to the restoration committee. 
Three of its four original towers remain, alongside tales of the White Lady ghost—believed to be Lady Margaret Butler, 15th-century resident and grandmother to Anne Boleyn.
Today, wander enchanting woodland paths, a serene lake, rose gardens, and exhibit halls. Former servants’ quarters now host the Butler Art Gallery, showcasing Irish and international art across centuries.
