Buttevant Castle was built by the Barry's around 1200 AD and was the chief residence of the clan Donegan, who rejected every Norman surrender move, until it was ultimately surprised and captured by a David de Barry, son of Philip. In 1206, Philip's eldest son William, was confirmed by King John and by Charter became Lord of Castlelyons, Buttevant and Barry's Court, where he soon afterwards built a castle.
