Local folklore holds that the stone was set up by St. Patrick. Stones of this kind, however, were erected in prehistoric times.
About one kilometre to the east, near the Kilcummin Holy well, stands the slender Carrowteelagh menhir.

About one kilometre to the east, near the Kilcummin Holy well, stands the slender Carrowteelagh menhir. A further 800 metres to the east, near Kilcummin and close to the beach, stand the two St Cumin’s Grave menhirs.

Menhirs are found across Europe, Africa and Asia, with a concentration in Western Europe, notably in Ireland, Great Britain and Brittany. In Ireland they are usually located in farmers’ fields and are heavily worn by weather and livestock. Theories about their purpose remain speculative, with hypotheses including rituals, territorial markers and elements of an ideological system. Standing stones are usually difficult to date, because they were set up in many different periods of prehistory.

About this kind of monument
Irish standing stones
Ireland is rich in menhirs, standing stones that are usually located in farmers' fields and heavily worn by the weather and by livestock. Menhirs are found across Europe, Africa and Asia, with a concentration in Western Europe, notably in Ireland, Great Britain and Brittany. Theories concerning their purpose remain speculative, with hypotheses including rituals, territorial markers and elements of an ideological system. Standing stones are usually difficult to date, because they were set up in many different periods of prehistory.
One Irish stone is well dated by its art. The Turoe Stone, a 1.2-metre granite boulder in the village of Bullaun, County Galway, probably dates to about 100 BCE to 100 CE. The top half is covered with a continuous abstract curvilinear design in the La Tène Celtic style, similar to the Castlestrange Stone in County Roscommon. It is National Monument number 327. For centuries the stone was a curiosity at a lios, a "fairy fort", some 3 kilometres away, before it was moved to Turoe Farm; in 2025 it was moved temporarily for conservation. The "fairy fort" name is a folk tradition.
Ogham, the early medieval alphabet of Ireland, was cut on the edges of some standing stones. In Ireland it is traditional to carry a stone up from the bottom of a hill and add it to the cairn at the top.
The Atlas treats isolated Irish stones as undated unless there is excavation or art to show their age.
When visiting, look at the surface for carving.
