What looks from a distance like a slight rise in ordinary farmland is in fact a sub-circular earthwork, roughly 26 metres north to south and 31 metres east to west, defined by a scarp and a fosse. A fosse is simply a ditch, typically cut to reinforce the defensive or enclosing function of an accompanying bank or mound, and here it traces an arc from the south-east, around the south and west, continuing north and north-east before being absorbed into a later field boundary.

The earthwork appears on the 1840 edition of the Ordnance Survey Ireland six-inch map, where it is drawn as an oval-shaped area enclosed by a bank, suggesting it was already a recognisable feature in the landscape well before anyone thought to formally record it. By the time the 1897 edition of the 25-inch map was produced, the feature was shown as a raised sub-circular area, and the traces of post-1700 agricultural reorganisation had already begun to cut across it. A field boundary running north-west to south-east absorbed part of the fosse along the northern edge, while a second boundary intersected the earthwork at its south-west. The site sits within a wider archaeological landscape: an enclosure lies approximately 80 metres to the north-west, and a hillfort, a type of large defensive or communal enclosure typically dating to the Iron Age, sits roughly 220 metres further in the same direction. The record was compiled by Fiona Rooney and uploaded to the national database in October 2021.

Because the earthwork is set in reclaimed agricultural land and is tree-covered, it is considerably easier to spot on aerial imagery than on foot. Google Earth orthoimages and a Digital Globe image taken between 2011 and 2013 both show the canopy clearly marking the outline of the feature. Anyone visiting the area should check current land access arrangements before approaching, as the site sits within working farmland. The low profile of the scarp means the earthwork reads best in raking winter light, when shadows lengthen and the ground is not obscured by summer growth. Looking for the point where the old fosse line meets the later field boundary along the northern edge gives a concrete sense of how later farming gradually worked its way around, and eventually into, something considerably older.
