This huge boulder, shaped like a chair, is the property of Mrs. McMonagle of Corrasheisk, Killygordon. A giant, long since dead, is supposed to have used it as a seat long ago. As an explanation of how the stone got there it is said that two giants over in Lismulladuff Glen - about three miles away- were testing their strength to see which could throw the stone the greater distance. The giant who won the test threw his stone on top of Cornasheisk Mt. and decided henceforth he would live there.
A little distance below the stone a huge tombstone marks the spot where the giant lies buried. The tombstone is cut out in the shape of the giants's own body. Writing can be traced on the upper surface of the stone but it is so blurred that it is impossible to decipher it. Local tradition has it that a great treasure lies buried in this grave.
The hill's also called Ballyarrell Mountain and the stone is on a steep south-facing slope. The story is from the Schools Collection of the 1930s which is currently being transcribed at duchas.ie.
