Ogham stones

Ogham stones are ancient Irish markers, typically made of stone, inscribed with a script called Ogham—an early alphabet used around the 4th to 9th centuries AD. These stones often served as memorials or boundary markers, with their distinctive linear inscriptions carved along the edge. The Ogham script features groups of strokes or notches representing letters, mainly names or important words. Found mainly in Ireland and parts of western Britain, the stones offer valuable insights into early Celtic language, culture, and social structures. They remain significant archaeological artifacts, reflecting the linguistic and artistic heritage of early Ireland.
