A roughly circular embanked enclosure, somewhere between fifteen and twenty metres across, was recorded on the Ordnance Survey six-inch map of 1837, the great nineteenth-century cartographic project that documented Ireland's landscape in extraordinary detail. By the time the next major survey edition was produced in 1930, it had vanished from the map entirely. Visit today and you will find no trace of it at ground level whatsoever.

Embanked enclosures of this kind are scattered across the Irish countryside and can date from a wide span of prehistoric and early medieval periods. They typically consisted of a low earthen bank defining a circular or near-circular space, sometimes used for settlement, sometimes for agricultural purposes, and sometimes associated with ritual activity. At fifteen to twenty metres in diameter, this one would have been a modest example. What happened between the 1837 survey and its absence from the 1930 edition is unrecorded. It may have been gradually levelled by ploughing or land improvement, both common fates for low earthworks in agricultural areas, or the feature may simply have been too faint by the later date to merit inclusion. The townland name, Abbeyhalfquarter, hints at some ecclesiastical connection in the broader area, though nothing in what is known about this particular enclosure links it to any religious foundation.
