Passing through Liscarroll in Co. Cork, on the way to visit the donkey sanctuary, we stopped at the remains of Castle Liscarroll (original foundation circa 13thC). It is closed to the public but serves as a nicely protected place for the cows to graze.
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.
