Roughly subcircular in shape and measuring just under ten metres across at its widest point, it is easy to walk past without registering its significance. The bank that defines it is broken by gaps on the western and northern sides, but these openings are thought to be later intrusions rather than original features of the design.

What makes this modest earthwork more than a simple boundary remnant is the raised trackway that extends from its southwestern edge for around thirty metres, connecting the enclosure to a nearby rath. A rath is a roughly circular earthen ringfort, one of the most common archaeological monument types in Ireland, typically associated with early medieval settlement and farmsteads. The trackway, then, suggests a functional relationship between the two features: the enclosure may have served as a subsidiary space, perhaps for livestock or some domestic purpose, linked deliberately to the larger defended settlement beside it. The detail was noted by McCaffrey in 1952, placing at least some awareness of the site in the mid-twentieth century, though the landscape around Lackanaloy Creek has changed little enough that the earthworks remain visible in the pasture.
