Rathlin O'Birne, Island off the coast of Donegal, Ireland
Rathlin O'Birne is a small, uninhabited island off the southwestern coast of County Donegal, Ireland, near the cliffs of Slieve League. A lighthouse stands on the island, marking the edge of this exposed stretch of the Atlantic coastline.
The island appears in early Christian tradition as a place where Saint Assicus, a companion of Saint Patrick, is said to have taken refuge during the 5th century. Over the following centuries, the lighthouse became the main mark of human presence before the island was eventually left uninhabited.
The island is tied to the legend of Saint Assicus, a coppersmith and companion of Saint Patrick, who is said to have sought refuge here. Visitors walking the rocky paths today move through the same bare landscape that once drew monks looking for solitude far from the mainland.
The island is accessible only by boat from the mainland, and the crossing itself offers views of the cliffs and open water. Visitors should bring food and weatherproof clothing, as there are no shops or shelters on the island.
The lighthouse on the island was the first in Ireland to be powered by nuclear electricity, a fact that stands out for such a remote and uninhabited place. This choice reflects how important this point was for ships navigating the northwestern coast.
