That is precisely what makes it worth knowing about. A rectangular enclosure once stood here, low-banked and tree-covered, the kind of earthwork that local people referred to, as they so often did across rural Ireland, as a fort. At some point in the 1960s it was levelled, and the land returned to tillage. No surface trace remained when the site was assessed.

Enclosures of this kind, defined by a surrounding bank and sometimes a ditch, are among the most common archaeological features in the Irish countryside. They served various purposes across different periods, from enclosed farmsteads to ceremonial or boundary functions, and a great many have been lost to agricultural improvement. The enclosing bank at Ballygiblin was modest by any measure, recorded at roughly two to three feet high before it was removed. Its rectangular form was noted as a distinguishing detail, since many comparable sites tend toward a roughly circular or oval plan. What the enclosure actually was, how old it might have been, and who built it, are questions that the ground can no longer answer.

There is nothing to find at the site today. Its value now is almost entirely as a negative example, a reminder of how much of the Irish archaeological landscape was quietly erased during the mid-twentieth century, often without record, often within living memory.
