Where an enclosure roughly thirty metres across once stood, defined clearly enough on the Ordnance Survey maps of 1841 to 1842 as a circular feature marked with hachures, the ground had been broken up and hollowed out by the time the next detailed survey was made. By 1897, the OS twenty-five inch plan was marking the same spot not as an ancient monument but as a large pit, labelled simply "Sand Pit (Disused)". The enclosure had been quarried away, probably for the sand beneath it, leaving only an absence where something far older had been.

Hachures, the short radiating lines used by cartographers to indicate a raised or banked feature, suggest the enclosure had some surviving earthwork form when the surveyors first recorded it in the early 1840s. Circular enclosures of this kind are common across Ireland, often the remains of early medieval ringforts, which were enclosed farmsteads typically defined by one or more earthen banks and ditches. Whether this particular example was a ringfort or something earlier is now impossible to say with certainty, since whatever physical evidence remained was removed before any archaeological investigation could be carried out. By the 1939 OS six-inch map, only a smaller depression about ten metres across was visible, and this shrunken hollow was later judged to have no archaeological significance in itself. The circumstantial case for the original feature having been a genuine monument, however, is strengthened by a second enclosure lying to the northwest, also recorded on the first-edition OS map as a circular earthwork of comparable character.
