The "Cliffs of Dooneen" is an Irish ballad made famous by Christy Moore. The song was written by Jack McAuliffe from Lixnaw, Kerry about the cliffs around Dooneen Point between Ballybunion and Beale which is where Bromore Cliffs are situated.
You may travel far far from your own native home
Far away o’er the mountains far away o’er the foam
But of all the fine places that I've ever seen,
There's none to compare with The Cliffs of Dooneen
Between 1700-1750 a volcano was reported near the site where the Devil’s Castle stands. It seems to have created some excitement at the time. Apparently a section of the cliffs which had been undercut by the sea fell, resulting in a section of newly exposed cliff catching fire and remaining hot for a number of weeks.
The learned people of the time came to the conclusion that the minerals in the rock came in contact with salt water resulting in a chemical reaction.
