A circular earthwork, roughly 36 metres across from east to west, lies beneath the grass, its outline too faint to read at eye level but legible from above. It is the kind of feature that disappears entirely into the everyday landscape until a satellite image catches it at the right angle, in the right light, and suddenly a near-perfect arc emerges from the texture of the field.

Circular earthworks of this general type are a broad category in the Irish archaeological record, encompassing everything from ring forts, which were enclosed farmsteads typically dating from the early medieval period, to enclosures of prehistoric origin whose function remains uncertain. At around 36 metres in diameter, this example sits within the size range commonly associated with domestic or agricultural enclosure, though without excavation or closer survey, its date and purpose remain open questions. What is known is that its outline survives, at least partially, in the soil and subsoil beneath the pasture at Grange More, detectable through the differential growth of grass above buried features, a phenomenon known as a cropmark or soilmark, and visible in aerial photography. The site came to wider attention through orthoimages, which are geometrically corrected aerial photographs that allow for accurate measurement and spatial analysis, and it was recorded in 2021 based on work by Jean-Charles Caillère.
