The one at Lios Ó Móine is a quieter presence. Sitting on a north-facing slope in rough grazing land, it has been parcelled up by later field boundaries that cut straight across its interior, dividing what was once a single enclosed space into quadrants. The geometry of modern agriculture has been laid directly over the geometry of early medieval life, and the two systems sit together in a state of permanent, unresolved overlap.

A ringfort, or rath, is an enclosed farmstead, typically of early medieval date, formed by one or more circular earthen banks with an internal ditch. The enclosure at Lios Ó Móine measures approximately fifty metres east to west. Its defining feature is a scarp, a cut or sloped edge in the ground rather than a built-up bank, running to the north, east, and west, reaching a maximum height of around one and a half metres. To the south and south-south-east the ground rises more sharply, at roughly three-quarters of a metre, suggesting the natural slope of the hillside was incorporated into the defensive and drainage logic of the site. Recorded alongside the ringfort is a possible souterrain, a type of underground stone-lined passage or chamber associated with early medieval settlements, often interpreted as a place for food storage or, in moments of danger, concealment. The place-name itself carries weight: Lios Ó Móine, in which lios is the Irish word for an enclosed fort or homestead, suggests the site was significant enough to name the townland around it.
