Wedge tombs, the most numerous megalithic tomb type in Ireland, are Neolithic to Early Bronze Age monuments typically consisting of a stone-built burial chamber that narrows towards the rear, often covered by a cairn or earthen mound. This one is ruined enough that its original dimensions cannot be fully recovered, but when Ruaidhrí de Valera and Seán Ó Nualláin surveyed it for their 1961 volume on Clare's megalithic tombs, they recorded a roughly circular grass-covered mound approximately 11.5 metres in diameter, rising to about 1.25 metres at its highest point near the western end of the chamber.

De Valera and Ó Nualláin described the chamber as oriented to the WNW, measuring around 2.5 metres in length and 1.7 metres wide at its open western end, narrowing to about a metre towards the rear. The roofstone had fallen and come to rest to the south-east, the southern sidestone was broken and displaced, and a later stone fence cutting across the northern end of the mound further complicated any attempt at precise measurement. A scattering of stones around the structure may represent outer walling, while four stones beyond the western front could be the remains of a kerb, a low ring of upright stones sometimes encircling such monuments, or alternatively the footing of an outer façade, a feature comparable to what was uncovered at a nearby wedge tomb excavated in Parknabinnia townland. The mound itself appears to abut rather than integrate with the tomb, suggesting it may be a later addition, and FitzPatrick (2008) proposed that the whole structure may have been reused as a boundary marker during medieval times.

The tomb does not stand in isolation. The surrounding field system, which spans multiple periods and townlands, is thought likely to include settlement traces contemporary with the tomb itself, similar to Bronze Age farming landscapes identified elsewhere on the Burren. The cashel of Cahermacnaghten, a stone-walled early medieval enclosure, lies roughly 340 metres to the north-west, and the land falling away to the east means that, even from this quiet and overgrown corner, the views range from north-west to south across the limestone country.
