What is recorded here

Oileán sa Tuaidh is a small islet in County Mayo where a circular granite lighthouse has cut through Atlantic darkness since 1838. George Halpin Senior shaped its tapering body and curving iron railings to guide ships past the northern coast, while storms battered the walls and humans climbed the spiral stair to keep the flame alive. The light changed from oil to electricity and finally to automation, but the stone still stands against the sea, marking the edge of the world for anyone who watches it blink.
