Measuring roughly seven metres north to south, eight metres east to west, and only forty centimetres high, it is the kind of feature that reads less as a monument than as a gentle irregularity in the ground. Yet it is not alone. It sits at the centre of a broader complex of earthworks, one that includes earthen enclosures, a linear earthwork, and what may be a barrow, a type of burial mound common across prehistoric Ireland, here retaining portions of a double bank along its edges.

The whole complex occupies a field that slopes gently westward toward the water, and the land has clearly had a difficult relationship with those who have tried to use it. Efforts to reclaim the ground for pasture have only partially succeeded; the field remains somewhat marshy, and that persistent dampness has, perhaps inadvertently, worked in the archaeology's favour. The sites are partially denuded as a result of the reclamation work, but enough survives to suggest that this was once a place of some significance in the local landscape. A survey of the Lee Valley area carried out by Michael Connolly in 1996 and 1997 recorded the complex in its current state, noting both what remained and what had been lost to agriculture.
