What is recorded here

An tOileán Iarthach is a rock island in County Galway where an 1857 lighthouse still stands with flared walls, square windows, and two keeper houses at its southern edge. For decades a human flame guided ships past the west end of Árainn, but since 2006 a solar light has taken that duty, leaving the stone chamber empty and the houses exposed to the Atlantic. The sea did not ask permission to occupy the island; it simply continued the work of marking its own edge.
