Measuring roughly 16.5 metres on its north-west to south-east axis and 15.2 metres across, it is defined by a scarp, the edge of a cut or built-up platform, and an external fosse, a water-filled or waterlogged ditch that would once have formed a deliberate boundary around the interior. At the north-eastern side, a later drainage ditch has been cut directly into that fosse, obscuring its original profile. The site is tentatively identified as a small moated site, a category of medieval enclosure typically associated with minor lords or well-off farmers who surrounded a domestic compound with a water-filled ditch as a practical and symbolic statement of status.

What makes the location quietly suggestive is its relationship to a nearby ecclesiastical site. About 150 metres to the south-west, on the opposite bank of the Kilcrow River, lies St. Corban's church. The pairing of a possible moated enclosure with a medieval church across a small watercourse is not unusual in the Irish landscape; secular and religious establishments often developed in close proximity, sometimes under the same patronage. The dedication to St. Corban is itself an uncommon one, and the two sites together hint at a small but coherent medieval settlement cluster in what is now an otherwise quiet and waterlogged stretch of County Galway.
