The ringfort at Highpark has been levelled, its banks worn almost flat by centuries of farming, yet the circular logic of the place persists. A scarped edge traces an oval roughly forty metres east to west and thirty-six and a half metres north to south, and if you know what you are looking for, the shape of an early medieval farmstead is still legible underfoot.

Ringforts, sometimes called raths, were the most common form of enclosed settlement in early medieval Ireland, typically built between the sixth and tenth centuries. They functioned as farmsteads, their earthen banks and ditches demarcating a household's territory and offering a degree of protection for livestock and family alike. The Highpark example follows a familiar pattern: a main bank defined by a scarped edge, an external fosse (a defensive ditch) roughly four and a half metres wide, and a counterscarp bank on the outer side of that ditch. There is also a gap of about four metres in the bank on the east-south-east, almost certainly the original entrance. The site was recorded on the 1923 Ordnance Survey six-inch map as an embanked circular enclosure, which at least fixes a point by which the earthwork's general form was still distinct enough to be mapped. The record was compiled by Denis Power and uploaded to the national monuments database in June 2013.

The field lies in gently undulating, poorly drained pasture, the sort of ground that has kept the land in grass rather than tillage for a long time, which is partly why anything survives at all. The site commands good views in all directions, a reminder that whoever chose this spot was thinking about visibility as much as convenience. A visitor approaching across the field should look for a very subtle change in ground level, the interior slopes gently downward to the south, and after rain the fosse line may be wetter and greener than the surrounding grass. There are no markers, no signage, and no formal access; this is agricultural land, and permission from the landowner would be the appropriate first step before setting out.
