It measures just 11.5 metres north to south, 8.5 metres east to west, and barely 0.75 metres in height, with two large stones visible on its northern side. What looks like an unremarkable coastal hump is, in fact, a passage tomb, a type of Neolithic monument in which a stone-lined corridor leads to a burial chamber at the centre, typically covered by a round mound of earth or stone. This one is recorded as Mound V within the Bremore passage tomb cemetery, a grouping of ancient monuments that rarely features on the well-worn circuits of prehistoric Ireland.

The site was first noted in the archaeological literature by Rynne in 1960 and formally listed as a passage tomb by Herity in 1974. Its quiet exterior conceals a good deal of internal complexity. A geophysical survey conducted under licence in 2006, with results reported by Gimson, detected a cairn of stones beneath the mound's surface covering what may be a central burial or cremation deposit. More intriguingly, seven isolated magnetic responses were identified arranged around the circumference of the mound. These anomalies are interpreted as small pits or areas of burning, a pattern that hints at ritual activity beyond simple interment. The coastal location also brought the site to wider attention when a constraint study was commissioned by Margaret Gowen and Company Ltd. ahead of a proposed port development in the area, and a separate fieldwalking and lithic analysis project was carried out by Collins as part of an MA study in 2007.

The monument is protected under a preservation order made under the National Monuments Acts 1930 to 2014 (PO no. 27/1976), which places legal obligations on how the site and its immediate surroundings may be treated. It sits in an area where coastal erosion and development pressure have historically made monument survival uncertain, so the preservation order carries real practical weight. Visitors approaching the site should be aware that it lies within a working coastal landscape; the mound itself is unexcavated and unenclosed, so what you are looking at is largely surface evidence, the two exposed stones on the north side and the subtle swell of the mound. The geophysical findings remain unpublished in any final excavation report, meaning the central deposit and the ring of pits are, for now, known only through instrument readings rather than direct investigation.
