The rath at Kinnagh, County Wexford, is not one of those. At ground level, in the pasture where it lies, there is nothing to see. The enclosure exists, as far as any visitor is concerned, only as a ghost in the grass, detectable solely from the air.

A rath is a ringfort, the most common class of monument in the Irish countryside, typically a roughly circular area enclosed by one or more earthen banks and ditches, used as a farmstead during the early medieval period. What makes the Kinnagh example quietly interesting is its shape. Aerial photography reveals not the usual circle but a D-shaped or subrectangular enclosure, running approximately 40 metres north to south and 35 metres east to west, with a notably straight side along the west. The boundary is defined by a slight fosse, a shallow ditch, which reads clearly as a cropmark on the aerial image, the buried feature affecting the growth of whatever is planted above it in ways the camera can catch even when the eye cannot. A possible entrance is visible at the eastern side, and there are traces of associated field boundaries nearby, suggesting this was not simply a defended homestead in isolation but the centre of a small agricultural landscape. The site sits in a gentle col, a low saddle of ground between slightly higher land to the north and south, a modest but deliberate choice of position that would have offered some shelter without sacrificing outlook.
