There are only five stones remaining, and even specialists cannot agree on what type of structure they originally formed. That uncertainty is itself part of what makes the site quietly compelling: most ancient monuments are at least classifiable, fitted into a known category of portal tomb, court tomb, or passage tomb. This one resists that tidiness entirely.

Three of the stones sit on the eastern side of a north-south field bank and drain, at the edge of woodland, and appear to represent two sides of a burial chamber. Roughly ten metres further south, on the western side of the same field bank, two additional stones stand near a disused trackway. Whether these belong to the same structure or are unrelated is unresolved. The remains are simply too sparse to draw conclusions. Megalithic tombs of this region were typically built during the Neolithic period, constructed as collective burial monuments and often covered by a cairn of stones or earthen mound, most of which has long since been robbed away or absorbed into the agricultural landscape. Here at Carnroe, even the cairn mound suggested by the hill's name seems to have left little behind.
