Historically and visually, the magnificent Kilkenny Castle at the southern end of the town is the jewel in the county's crown. With beautifully tended public gardens and a magnificent view of the Nore, the twelfth-century fortress has undergone frequent restoration and renovation during the five and a half centuries in which it was owned by the Butler family; and throughout the six decades since the Butlers donated it to the public. The resulting palimpsest of styles from different architectural eras (Gothic, Classical, Victorian and Tudor) is an effect that is repeated throughout Kilkenny. A very worthwhile tour of the Castle is usually oversubscribed and it is advisable to make arrangements in advance. The pretty old stables of the Castle now house the Kilkenny Design Centre, a mecca for those wishing to purchase Irish crafts. Behind the Centre, meanwhile, are a selection of craft workshops.
