What once stood here was a ringfort, the kind of early medieval enclosed settlement that once numbered in the tens of thousands across Ireland, built by farming families as a combination of homestead and status marker. This particular example was a substantial one, roughly circular and measuring approximately 46 metres north to south and 44 metres east to west, its perimeter defined not by an earthen bank alone but by a wide fosse, a defensive ditch cut into the ground to a width of around six metres. By the time a revised Ordnance Survey map was drawn up in 1947, the enclosure was clearly enough defined to be recorded in detail. By around 1970, it had been levelled entirely.

The destruction of ringforts during the mid-twentieth century was far from unusual. Land reclamation, agricultural improvement schemes, and the arrival of mechanical earth-moving equipment made the removal of ancient earthworks a practical rather than a controversial act for many farmers of the period. At Damerstown, the rolling grassland has been reclaimed and the monument cleared, but the ground itself has not entirely forgotten what was done to it. The location of the former enclosure remains legible as a disturbed, rocky area within the field, the subsurface disrupted in ways that the surrounding land is not. It is the geological equivalent of a scar, the soil and stone unsettled where the fosse was filled and the banks were pushed flat, visible to anyone who knows to look for it.
