It gives itself away only from the air, appearing as a cropmark, where buried features cause crops growing above them to ripen at slightly different rates, producing faint rings or lines readable in aerial photographs but otherwise undetectable at soil level.

The enclosure is univallate, meaning it was defined by a single encircling bank or ditch rather than the multiple concentric rings that characterise more elaborate sites. Circular enclosures of this kind are among the most common archaeological features in the Irish landscape, associated broadly with the early medieval period, though without excavation it is impossible to assign a confident date or function to any individual example. They served variously as farmsteads, ceremonial spaces, or enclosures for livestock. This one was identified through the Cork Archaeological Survey aerial photography programme, which systematically recorded cropmark sites across the county and brought a number of otherwise unrecorded features into the inventory.
