Only half of it remains legible in the landscape; the rest has been swallowed by later field boundaries and the creeping advance of trees and bushes. What is left is a semicircular arc, running from the south-east around through the west to the north-west, defined by an earthen bank and an external fosse, the shallow ditch that would once have reinforced the enclosure's defensive or boundary function. A ringfort, broadly speaking, is a circular or oval enclosure of early medieval date, typically used as a farmstead and defended by one or more banks and ditches; they are among the most common archaeological monument types in Ireland, yet each one carries its own particular history of use and decay.

The first-edition Ordnance Survey six-inch map records the full, roughly oval shape of the enclosure, oriented east to west and measuring approximately 35 metres across at its widest. That cartographic ghost is now the clearest evidence that this was once a complete monument. At the north-west and south-east, a farm field boundary slices through what remains, and to the north of that line the original earthworks have been obscured entirely. Faint traces of a possible outer bank, which would suggest a more substantial original construction, survive along the southern and western arc. The estate itself was the former Clonbrock demesne, the grounds of a landed property whose organised landscape of fields and plantings has clearly left its mark on the monument's condition over the centuries.
