From the air, or rather from satellite, the picture changes entirely. A near-perfect circular cropmark emerges, roughly 70 metres across, its outline traced by the differential growth of whatever crop happens to be in the ground. The pattern betrays an ancient enclosure, the kind of roughly circular ditched boundary, sometimes surrounding a settlement or ceremonial site, that appears repeatedly across the Irish countryside. The fosse, a defensive or boundary ditch, reads about 10 metres wide in the satellite imagery, with what appears to be a substantial entrance gap of around 14 metres in the eastern quadrant.

What makes this site quietly interesting is its paper trail, or rather its absence of one. When the Ordnance Survey first mapped this part of Kilkenny in 1840, nothing was recorded here. It was only in the 1900 revision of the six-inch map that surveyors noted something, marking an irregular area of roughly 56 metres in diameter with a dashed line just north of a field boundary running west-northwest to east-southeast. Dashed lines on Ordnance Survey maps of that period often indicated something observed but not fully understood, a feature that did not quite fit the neat categories of the time. The enclosure sat in that ambiguous zone, half-seen, loosely sketched, then largely forgotten. It took satellite imagery captured in June 2005 to bring it back into focus, the cropmark revealing a coherent circular form that the nineteenth-century surveyors had only partially glimpsed.
