Enclosures
Beneath the tilled fields of Seskin in County Tipperary, a cluster of ancient enclosures lies completely invisible to anyone walking the ground.
No earthwork, no ridge, no depression gives anything away. The only reason we know these structures exist at all is because, from the air, the buried remains betray themselves through the crops growing above them, producing subtle variations in colour and growth rate that, under the right conditions, read clearly as geometric shapes against the surrounding field.
These shapes, known as cropmarks, reveal a sub-circular enclosure on a gentle north-facing slope in gently undulating farmland, and it does not sit alone. To the north-east lies a conjoined enclosure, meaning one that shares a boundary or connects directly with another, suggesting deliberate planning rather than isolated settlement. To the north-west sits a further separate enclosure, and to the west, three more conjoined enclosures form what appears to be a coherent grouping. An associated field system rounds out the picture, hinting at an organised agricultural or settlement landscape that once occupied this part of Tipperary. The cumulative effect, visible only in aerial photographs, is of a place that was once genuinely busy with human activity, its boundaries and divisions carefully laid out across the slope.
Cropmark archaeology of this kind depends on specific conditions: dry summers, low-growing cereal crops, and the right angle of light. The buried ditches or walls that once defined these enclosures retain moisture differently from the undisturbed soil around them, and that difference is what the crops express. On the ground today, there is nothing to see. The tillage continues, the slope looks like any other field in this part of Tipperary, and the enclosures persist only as data, preserved in aerial photographs and the soil itself.
