The monument sits on a moderate south-south-westerly facing slope in pasture, and its alignment with the boundary between Doon North and Doonsouth suggests that the old earthwork was absorbed into the administrative geography of the landscape long after whoever built it had gone. That kind of layering, where one era's structure quietly becomes another era's legal line, turns up often in the Irish countryside, but it is rarely so legible.

The 1840 Ordnance Survey six-inch map recorded the site as a raised circular area enclosed by a wide berm, and noted an Ordnance Survey datum point at 610 feet above sea level on the same sheet. When the Archaeological Survey of Ireland visited in 1999, they found considerably more complexity than a simple raised circle. The surveyors, Alison McQueen and Vera Rahilly, recorded a monument roughly 33 metres in diameter, comprising an inner earth and stone bank, a fosse (a defensive ditch), an intervening bank, a partial outer fosse, and the remnants of a counterscarp, the raised lip on the far side of a ditch that increases its defensive effect. The causewayed entrance, a gap with a raised approach across the ditch, measures five metres wide at the south-east and appears to be original, though it may have been widened at some point in the modern period. The inner bank has been largely levelled to a scarp, but the deep intervening fosse remains visible all the way around. A later field boundary cuts across the intervening bank to the north-north-west and slices across the outer edge of the inner fosse, and north of this boundary, the monument has been entirely erased.

The site sits in working pasture on a hillslope that opens out to long views from the south-east around to the north-west, which gives some sense of why the position was chosen in the first place. Aerial imagery from 2011 to 2013 and a Google Earth image from November 2018 both show the enclosure as a sub-oval, tree-lined shape, so the ring of trees is likely the clearest way to orientate yourself when approaching across the field. The south-western interior is raised relative to the north side, a deliberate levelling against the slope. The best-preserved section of the intervening bank runs from the west to the north-west, and the partial outer fosse is most visible from the north-east around to the south-east.
