Enclosures
At Garranejames in County Cork, a circular enclosure lies buried beneath farmland, invisible to anyone walking the field above it.
It exists, as far as present knowledge goes, only as a cropmark, a faint differential in the growth of crops that becomes legible from the air. Where buried ditches or banks alter the soil's moisture and nutrition, the plants above respond, growing taller or shorter, greener or more parched, tracing the outlines of structures long since levelled. From the air, that difference in growth reveals a bivallate enclosure, meaning one defined by two concentric rings of earthworks, a form associated broadly with the early medieval period in Ireland.
The enclosure was identified through aerial photography by Dr D.D.C. Pochin Mould, a scholar and aviator whose aerial reconnaissance work made a significant contribution to Irish archaeological discovery during the mid-twentieth century. The site sits in level tillage ground, which is precisely the kind of terrain where cropmarks show most clearly and where, paradoxically, ploughing over centuries has the greatest capacity to erode or destroy what lies beneath the surface. The entrance appears to have faced east, oriented towards a relict stream bed running north to south, a detail that hints at how the original occupants related to the local landscape, water sources and boundaries shaping where people chose to build and how they approached their own enclosures.
