The Giant's Causeway in County Antrim is a geological fact that triggered the tale of two giants, Finn MacCool and a rival across the sea in Scotland, Benandonner. The unusually-shaped columns of basalt rock were formed many millions of years ago in a river valley when the now island of Ireland was a part of a larger continental mass.
