Dún Crocbhur is one of those forts that will  simply bring an overwhelming sense of sheer beauty and dramatic scenery. It will also definitely be one of the best fort experiences you could have in Ireland  because of an impressive intricate design and complete mystery surrounding who built it and its purpose. Classified as a National Monument also because of its design, Dún Crocbhur is the largest stone fort on all three Aran Islands and stands defiantly at the highest point of the island with protective nature and is in full view no matter where you are.
