The enclosing bank has been worn down to a shadow of its original form, rising barely thirty centimetres above the surrounding ground on its outer face and fifty centimetres on the inside. At its best-preserved stretch along the western arc, it spreads to about six metres in width, suggesting something considerably more substantial once stood here. The interior, roughly forty-two metres east to west and at least fifty metres north to south, is completely featureless, with a slightly hollowed, dish-like surface.

Enclosures of this type are a common but poorly understood element of the Irish rural landscape. They may represent the remains of a ringfort, a circular or oval earthwork that served as a defended farmstead during the early medieval period, typically enclosed by one or more earthen banks and external ditches. What makes this particular example unusual is the complete absence of any ditch, either inside or outside the bank. Ditches were generally dug to provide the material for the bank itself, so their absence here raises quiet questions about how the enclosure was constructed, or whether what survives has been so heavily modified over the centuries that the ditch has simply vanished. The northern extent of the site has also been cut into by a wood, meaning the full original dimensions are no longer readable on the ground. The site was recorded by Michael Connolly during a survey of the Lee Valley area carried out between 1996 and 1997.
