The enclosure in question carries a preservation order under the National Monuments Acts, yet when surveyors last looked, there was no evident trace of it remaining on the ground. The order protects something that has, to all appearances, vanished.

The feature was first recorded in 1983 by David Sweetman and Muiris de Buitléir of the National Monuments Service. What they found was an enclosure, a category of monument that in the Irish archaeological landscape can mean anything from a ringfort, the circular earthen bank of an early medieval farmstead, to a prehistoric field boundary or ceremonial enclosure. By 2012, when an archaeological assessment was carried out in connection with proposed alterations to hole 13 of the Old Head Golf Links, the site could no longer be identified on the ground. The assessment was prepared by M. Hurley and submitted in connection with works at the same headland where the enclosure had once been noted. The timing and context suggest the intervening decades had not been kind to whatever earthwork or surface feature Sweetman and de Buitléir originally recorded.
