Walk the field today and the grass offers no clue, no rise in the ground, no scatter of stone. The enclosure here exists, for most of the year, only on paper. Yet under the right conditions it reappears, briefly and unmistakably, written in the colour of stressed vegetation.

The site sits on a gently south-facing slope, currently under pasture. What lies beneath is an enclosure, most likely the remains of a ringfort or similar circular boundary feature of the early medieval period, though the ground keeps that detail well hidden. Ringforts, which served as enclosed farmsteads from roughly the fifth to the twelfth century, were typically defined by one or more earthen banks and ditches. Where the bank has been levelled and the ditch filled over centuries of cultivation and grazing, the buried ditch can still betray itself in dry summers. During drought conditions, grass roots reach deeper and find the looser, moister soil that once filled the ditch, staying greener and growing more vigorously than the surrounding pasture. The result is a cropmark, a ghost ring that surfaces in the field when rainfall is scarce and the difference between soils becomes visible from above or even from the field boundary. Local knowledge at Meelaherragh holds that this is precisely what happens here, the ring showing up clearly as conditions dry out.
