In 1375, the castle was granted to James Butler, after he was made Earl of Ormond for his loyalty to Edward III. The first Baron of Cahir was not created until 1542 and for the next century, the castle was the center of conflict between nobles supporting alternately Catholics or Protestants and cousins fighting over inheritance.
Jim of course had to pose over the privy (toilet) which was basically a hole which opened out to the side of the castle.
