What is recorded here

Greencolly Fort stood on the Galway-Clare boundary as a sixty-metre circular enclosure opening onto a western cliff, but human activity or natural erosion levelled the site before 1922. A small boulder cairn marks the vanished fort today, preserving the shape of a place that no longer shows its own walls.

On the summit of a hill right on the Galway-Clare county boundary. Marked on the 1838 edition of the 1st OS 6-inch map as a subcircular enclosure (c. 60m N-S) opening onto a cliff edge to the W. Evidently levelled by the time of the 1922 edition of the map when the words ‘(Site of)’ are appended. No visible surface trace survives. A small cairn of boulders, most likely a trigonometrical cairn, occupies the site. Compiled by: Galway Archaeological Survey, UCG Date of upload: 29 July 2019

Greencolly Fort, Leagh South is a likely early-medieval ringfort situated on a hilltop at the Galway-Clare boundary, marked on the 1838 Ordnance Survey map as a subcircular enclosure. Its location and form suggest a defensive or agricultural function, while its association with fairy lore is implied by the common Irish tradition linking such forts to supernatural beings.
