About the script
Ogham is an early medieval alphabet used to write Old Irish and, occasionally, Latin or Pictish. It consists of strokes and notches carved along a central stem line — the flesc — and reads from bottom to top on vertical inscriptions, or left to right in its modern horizontal form.
The earliest inscriptions date to the 4th century AD, though the alphabet may be older. Over 400 Ogham stones survive across Ireland, with concentrations in Kerry, Cork, Waterford, and across the Irish Sea in Wales and Scotland.
Each letter is named after a tree or plant — Beith (birch), Luis (rowan), Fearn (alder) — giving the alphabet a deep connection to the natural world. The letter names form the Beith-Luis-Nion, the traditional Ogham ordering still used today.
Ogham inscriptions were typically memorial stones marking territory or commemorating the dead. The formula is usually simple: the name of a person, their father's name, and their tribe or people.
Despite its age, Ogham has never entirely disappeared. It remains a living symbol of Irish identity and a bridge between the modern Irish language and its oldest written roots.
The letters
Twenty-five letters in four groups — consonants on the right, left, and crossing the stem, with vowels as diagonal cuts. Explore the full alphabet →
In the landscape
Hundreds of Ogham stones still stand across Ireland — in fields, in church ruins, built into walls. Kerry and Cork hold the greatest concentrations, but stones appear as far north as Ulster and across the sea in Wales and Scotland.
