Enclosures
At Carrignashinny in County Cork, there is an archaeological site that no one can currently see.
The enclosure here exists only as a cropmark, a ghostly outline visible from the air when differential growth in a crop reveals buried features beneath the soil. Where a buried ditch or bank interrupts the ground, the plants above it grow slightly differently, a little taller or shorter, greener or more parched, depending on how moisture and nutrients are retained or drained. From ground level, there is nothing. From above, a shape emerges.
The shape in question is a univallate oval enclosure, meaning a roughly oval area defined by a single surrounding bank or ditch. These kinds of enclosures are found across Ireland and date most commonly to the early medieval period, though some are considerably older. They were used variously as farmsteads, burial grounds, or places of ritual, and in the Irish landscape they tend to survive as slight earthworks or, as here, as nothing more than a trace in the soil. The cropmark at Carrignashinny was identified through aerial photography by Dr D. D. C. Pochin Mould, a writer and aerial surveyor who documented many such sites across Ireland during the mid-twentieth century. The site sits in level tillage land, the kind of flat, well-worked ground that is particularly good at preserving and revealing cropmarks, precisely because it is regularly ploughed and planted rather than left under permanent pasture.
