Like medieval standing stones, the surviving fragments of the north and east walls date from the 13c. In 1252 John de Cogan was permitted to have a weekly market and annual fair beside the castle, then known as Castle More. In 1276 - 1281 it underwent repair when in royal hands, and in 1439 acquired by the Earl of Desmond. The Barretts took possession in the 17c, but forfeited the castle as Jacobites during the 1690s.
