 Barryscourt ceased to be main residence of the Barry family in 1617, but was evidently still an important fortification for many years afterwards, as it was attacked and captured in 1645, during the Irish Confederate War.The marks caused by the impact of cannonballs during this attack can still be seen on the castle walls.Barryscourt castle eventually fell into disuse, and a house was built by the Coppinger family (who had taken over the property from the Barrys) next to the castle in the early 18th century; this house has long since disappeared.
