This Ogham Stone lay partly buried on the Derrynane strand until the 1940s when it was moved to its present location.
The stone is of sandstone grit and stands 2.1m high. What is special about this stone, is that the markings on it are the earliest written form of the Irish language, Ogham.
Each letter of the ogham alphabet is composed of from one to five parallel lines or notches. These can be placed on, to either side of, or diagonally across a stem-line which is usually formed by the angle of a pillar stone. The ogham script is an alphabet thought to be based on the Roman alphabet.
The earliest use of ogham may date to the fourth century AD. The form of ogham inscriptions is commemorative and some ogham stones may therefore mark burials. The inscriptions are normally read from the bottom up.
The inscription is severely eroded. It was read by Macalister R.A.S. (Corpus Inscriptionum Insularum Celticarum, 1945) as:
ANM LLATIGNI MAQ M[I]N[E]RC M[UOCOI]
Q[. . . ]CI
Below is a table which interprets the letters of the Ogham alphabet as names of trees or shrubs.
