The Aran Islands lie in the middle of Galway bay and consist of three islands. Inishmaan, Inisheen, and Inishmor. Inishmor is home to the mysterious and imposing ring fort Dun Aengus. It is situated on the precipice of a 300ft ocean cliff. The rocks are always slippery and treacherous from the constant rain and ocean spray. No one really knows who built Dun Aengus. It is thought that perhaps the long disappeared Firbolg people built it after being driven from the West of Ireland to Scotland and then back to the West again, finally ending up on the Aran Islands where they scratched out a living on the barren rocky shores.
