No earthwork bank survives above ground, no ditch cuts visibly across the soil. What betrays its presence is a cropmark, the faint differential in how crops grow and ripen over buried features, which from the air traces the outline of a roughly circular enclosure approximately 45 metres in diameter. A single wide fosse, the term for a defensive or boundary ditch, defined its perimeter, running to somewhere between three and four metres in width. It is the kind of site that could be crossed daily without any suspicion that something significant lies just beneath.

Ringforts, known in Irish as raths when defined by earthen banks and ditches rather than stone, were the most common form of rural settlement in early medieval Ireland, typically serving as enclosed farmsteads from roughly the fifth to the twelfth centuries. Thousands survive across the country in varying states of preservation, but many, like this one in Coddstown Little, survive only as buried traces detectable through aerial observation. The enclosure sits within a broader field system in the area, though whether the two features are related or belong to entirely different periods remains uncertain. Roughly 20 metres to the east lies a separate ring-ditch, a circular ditched feature often associated with prehistoric burial or ritual, and the two fosses nearly meet on the western side of that ring-ditch, suggesting a landscape that accumulated distinct uses across a very long span of time. The cropmark was recorded on aerial photographs taken in July 2006, and is also visible on earlier aerial survey material from around 2000.
