The National Monuments Service's description

In a flat expanse of wet pasture, formerly a lake, which is named Ballybeg Lough on the 1838 OS 6-inch map.
This possible crannog is shown on the 1838 OS 6-inch map as a circular island, named ‘Gull Island’, located in the centre of Ballybeg Lough; by the time of the 1930 edition, the lake had been drained and the island is not shown. It consists of a low, subcircular grass-covered rise or platform (15.4m E–W; 14.5m N–S) defined by a low, broadly sloping scarp (H 0.4-0.5m), and is distinguished by a covering of rich green grass which differs from the surrounding rough bog sedges. A band (Wth 3m) of rushes encircles it. The platform appears to be composed of peaty soil incorporating some stones, but no features are visible to definitively confirm that it is an artificial construction rather than a natural island. A few hawthorn, holly and willow bushes grow around the perimeter.
