A rath, which is an enclosed ringfort typically built during the early medieval period as a defended homestead for a farming family, sits just below the crest of the drumlin's north-facing slope. What makes this one quietly interesting is how little of it remains above ground, and yet how clearly its shape can still be read in the landscape if you know where to look.

The site measures approximately 29.5 metres north to south and around 25 metres east to west. Most of its original perimeter bank has been lost, but a surviving scarp to the north-east, roughly 1.9 metres high and 1.5 metres wide, gives a sense of how the enclosure once stood. The southern arc of the perimeter can also still be traced. The interior has not escaped modification: a field bank running east to west bisects it, and a second bank curves around the south-western and western edges, following the old perimeter line. These later agricultural intrusions are typical of what happens to raths over centuries of continued land use. The site appears on McCrea's map of County Monaghan, surveyed in 1793, which confirms it was a recognisable feature of the landscape well before modern cartography formalised it on the Ordnance Survey six-inch maps that followed.
