Trees have colonised both the interior and the perimeter, so that what was once an open enclosure for early medieval life now exists inside a wood, absorbed into the demesne of a later era entirely.

A rath, as this type of earthwork is also known, is a roughly circular enclosure of early medieval date, typically built to protect a farmstead and its occupants. They were constructed from earth rather than stone, the spoil from a ditch thrown inward or outward to form a raised bank. This example sits on a slight south-facing slope at the south-western edge of a wood within the Garryrickin House demesne. It measures about 28 metres across internally on its north-west to south-east axis, and retains a reasonably legible profile: a bank roughly 3 metres wide and rising about 1.5 metres above the interior, a flat-bottomed external fosse 4 metres wide and 1.5 metres deep, and an outer bank 4 metres wide. That outer bank survives along the south-south-west to east-south-east arc, indicating this was a bivallate rath, meaning it had two concentric earthen ramparts rather than the single bank more commonly seen. The additional defensive ring would have marked out the enclosure as a settlement of some status. Gaps in the main bank at the north-west and south-east are likely to indicate original entrance points, though later disturbance cannot be ruled out.
