Aerial photographs have revealed a cropmark, a phenomenon where buried features affect the growth of surface vegetation unevenly, causing faint differences in colour and height that become legible when seen from above. What emerges is a near-perfect circular enclosure, approximately 25 metres in diameter, defined by a single fosse, that is, a defensive ditch, with a break in the southeast that marks the original entrance.

Ringforts, also called raths, were the dominant form of rural settlement in early medieval Ireland, typically dating from roughly the sixth to the twelfth century. Most were enclosed farmsteads, the fosse and accompanying bank serving less as military defences and more as a boundary marking status, keeping livestock in and wolves or raiders out. The example at Loginsherd sits on fairly level ground, which is itself a useful piece of information. Ringforts were frequently sited on slopes or elevated positions for drainage and visibility, so a level setting is a mild curiosity, perhaps reflecting the particular agricultural circumstances of whoever chose to build here. The site has left no surface trace that would alert a passing walker; its existence depends entirely on the faint, seasonal legibility of buried soil.
