4 Clomantagh Castle, County Kilkenny
Tucked away in the heart of Ireland's Ancient East, Clomantagh Castle is an intriguing jumble of styles. Part medieval tower house, part 19th century farmhouse, the building also boasts a Sheela-na-Gig (an ancient pagan fertility symbol) carved into one of the stones.
In its time, Clomantagh's been owned by everyone from a ne’er-do-well aristocrat (yes, we're looking at you, Piers Butler, 8th Earl of Ormond) to the local vet. Now, it's safely in the hands of the Irish Landmark Trust but it's available for hire for any wannabe kings or queens of the castle.
