In the pastureland of Coogue, a low mound rises just enough from the surrounding hilly terrain to suggest it was not always simply part of the field.
At roughly 20 to 25 metres across and about 2 metres high, with a flattened top some 10 metres in diameter, it has the proportions of a deliberate construction rather than a geological accident, though it may well incorporate a natural rise that made the spot attractive in the first place. A shallow curved depression at the south-western base, around 2 metres wide and 0.3 metres deep, appears to be the remnant of an external fosse, the kind of encircling ditch that would originally have defined and defended the perimeter of an enclosed site. That it can only be traced along one arc suggests either that the rest was never completed or, more likely, that centuries of agricultural use have worn the evidence away.
The site has a paper trail of sorts, visible on the Ordnance Survey's six-inch map of 1838 and again on the 25-inch plan, both of which record it as a circular enclosure with a diameter of around 25 metres. By the time the 1917 OS six-inch revision was made, the recorded diameter had shrunk slightly to about 20 metres, and the northern edge had already been truncated by field boundaries, with a laneway cutting into the eastern side. That kind of gradual attrition is common with earthworks in actively farmed landscapes. The mound has been further altered by its incorporation into a later field fence system, and remnants of those fences still overlie the scarp at the north-west and along the north-north-east to south-east arc, with traces of stone facing visible at the base of the scarp on the western side. What the original structure was, whether a ringfort of the early medieval period or something older, is not recorded, and the mound's history before the first mapping remains open.
Access to the site is complicated by a dense stand of conifers that now grows across the mound, making close inspection difficult and obscuring much of the surviving detail. The shallow fosse at the south-west is probably the clearest feature still legible from the outside, and the modified scarps at the north-west give some sense of how thoroughly later farming activity has reshaped what was once a more distinct enclosure.
