Roughly seven metres across, it is defined by a low bank of stone and sod, now only about forty centimetres high and a little over a metre wide, running from west-northwest to north-northeast. What survives is, in all likelihood, only a fragment of whatever was originally here.

The enclosure's eastern side has been cut through by a later northeast-to-southwest bank, one that formed the western boundary of what was once the Coronation Plantation. The working assumption is that much of the original enclosure bank was deliberately robbed out, its stone and sod material reused to build this newer boundary. It is a pattern familiar across the Irish uplands, where older field monuments were quietly dismantled to serve more recent agricultural or estate purposes, leaving behind only the portions that happened to escape the clearance. The Coronation Plantation name points to an episode of organised land management, though the enclosure itself is almost certainly older, its original function, whether a small agricultural pen, a structure foundation, or something else entirely, left unresolved by what remains on the ground.
