It is a wedge tomb, the most numerous type of megalithic monument in Ireland, built during the late Neolithic and early Bronze Age as a collective burial chamber. What makes this particular example worth pausing over is the precision of its surviving architecture, modest in scale but coherent enough to read clearly across several thousand years.

The gallery runs roughly east-south-east to west-north-west and measures approximately 4.7 metres in length. A wedge tomb takes its name from its characteristic shape: wider and taller at the western end, narrowing and lowering as it extends eastward, so that the internal space tapers like a stone funnel. Here that profile is well preserved. Four stones form the northern wall, at least three the southern, and a row of six buttress-stones runs along the outside of the northern wall, the whole sequence terminating in a façade stone at the western end. Two overlapping roofstones still cover the eastern section of the gallery. The western orientation is typical of the type and is thought to reflect a deliberate alignment with the setting sun, though the precise ritual meaning remains a matter of interpretation. The catalogue of the monument was compiled by Ruaidhrí de Valera and Seán Ó Nualláin in their Survey of the Megalithic Tombs of Ireland, published in 1982, which remains the standard reference for monuments of this class across Munster.
