Passage tombs are among the oldest monumental structures in Ireland, built by Neolithic communities as collective burial places, their defining feature being a stone-lined corridor leading to a central chamber. This one is modest in scale but precise in construction, which is part of what makes it quietly arresting.

The cairn measures 7.5 metres in diameter and rises to a height of 1.6 metres, a compact but deliberate mass of accumulated stone. What survives most clearly is the kerb, a boundary ring of seven granite slabs set orthostatically, meaning they are placed upright on their ends rather than laid flat, anchoring the edge of the mound and giving it a defined, purposeful outline. That seven slabs remain in such clear arrangement, despite the peat that has accumulated around and over the structure, suggests the cairn has not suffered the worst of the disturbance that has claimed so many comparable monuments elsewhere in the country. The use of local granite ties the tomb to the broader Wicklow upland landscape, a region that preserves a notable concentration of prehistoric remains across its hills and boglands.
