It is the kind of site that exists, in a sense, more in photographs than on the ground.

The enclosure was identified through aerial photography by Dr D.D.C. Pochin Mould, a prolific recorder of the Irish landscape whose work captured many such traces before they were lost entirely to ploughing and development. What she photographed at Lehenaghmore is classed as univallate, meaning it had a single encircling bank or wall rather than the multiple concentric rings found at more elaborate sites. Circular enclosures of this type, sometimes called raths or ring-forts depending on their construction, were the most common form of rural settlement in early medieval Ireland, typically serving as farmsteads for a family and their livestock. A diameter of around thirty metres places this example at the smaller end of the scale, modest even by the standards of its type.
