Liscarroll (Irish: Lios Cearúill, meaning 'Carroll's ringfort')[2] is a village in County Cork, Ireland.

It may well have been built by David de Barry who died in the late 1270s and who had served as justiciar (the king's chief representative in Ireland) in the 1260s.

A sustained artillery bombardment during this battle caused considerable damage to the walls, making it indefensible, a fate suffered by many castles when cannon came into common usage.

[5] The castle is the subject of an 1854 poem by Callaghan Hartstonge Gayner which concludes: Beneath its folds assemble now, and fight with might and main, That grand old fight to make our land "A nation once again", And falter not till alien rule in dark oblivion falls, We’ll stand as freemen yet, beneath those old Liscarroll walls.

There is a ringfort close to the village, approximately 30 metres (98 ft) in diameter which dates to between the fifth and tenth century.
