The tomb is a wedge tomb, a type of megalithic structure built during the late Neolithic and early Bronze Age, typically characterised by a long, wedge-shaped gallery that narrows toward one end and was used for communal burial. This particular example has been reduced by time and disturbance to a gallery just 2.1 metres long and roughly 0.7 metres wide, oriented along a south-west to north-east axis. Two opposed sidestones and a septal stone, a dividing slab set across the interior, form its surviving core, and an additional stone outside the south-western end of the more southerly sidestone may indicate that the gallery wall was once doubled, a feature seen in other wedge tombs where extra structural support or ritual separation was intended.

The monument was documented by Ruaidhrí de Valera and Seán Ó Nualláin in their 1982 survey of megalithic tombs across Counties Cork, Kerry, Limerick, and Tipperary, the fourth volume of their comprehensive national survey. Their work recorded not only what survives above ground but also what the ground itself suggests about the original scale of the structure. A slight depression extending approximately 1.5 metres beyond the eastern end of the gallery points to the possibility that the tomb was once considerably longer, with the eastern portion having collapsed or been removed entirely over the millennia. Several displaced stones scattered around the site reinforce the sense of a structure that has contracted significantly from its original form, leaving only its most robust elements still recognisably in place.
