Look closer and the structure reveals itself: a kerbed cairn, meaning a mound of stones or earth deliberately edged with a ring of larger stones to define its boundary, measuring ten metres across and still standing roughly eighty centimetres high after what are likely thousands of years of weathering and disturbance.

The cairn is not an isolated feature. It belongs to a cluster of prehistoric sites on these same slopes, suggesting that this particular corner of Wicklow held some sustained ceremonial or funerary significance for the communities who shaped the landscape here long before written records began. The surrounding fosse, a ditch that in this case retains enough moisture to remain partially waterlogged, measures between three and four metres wide and around a quarter of a metre deep. Whether it was always intended to hold water, or whether that is simply the result of ground conditions over millennia, is unclear. What is evident is that the central area of the mound has been disturbed at some point, a common fate for cairns that were later assumed to contain grave goods worth investigating, though no specific account of any such interference survives for this site.
