 People who adhered to Catharic principles were held to be anti-Catholic heretics and, as narrated by McCaffrey, "their treatment was savage and merciless - heretics and their sympathisers were often either slaughtered or burned alive at the stake".The castle remained in use, seeing repeated conflicts, such as the Hundred Years War(1337-1453) between England and France, and the French Wars of Religion (1562–1598) between Protestants and Roman Catholics during which it was partly destroyed.It was then abandoned for approximately 400 years.
