A curvilinear earthwork roughly 80 metres across traces a curved line through the soil at Kilshenane, its defining bank barely rising above the surrounding grass. At its most pronounced, the bank stands only 35 centimetres high on the exterior and 20 centimetres on the interior side, with a total width of just under six metres. Where the earthwork curves to the south-east and south-west, even that modest bank diminishes further into a scarp, a simple slope in the ground with no raised edge at all, only 15 centimetres high. To walk across it would be to feel, rather than see, the faintest undulation underfoot.

What makes the site legible at all is aerial photography. Crop marks, the subtle variations in colour and growth rate that cultivated or grassy vegetation shows above buried or disturbed ground, reveal the full outline of the earthwork in a way that ground-level inspection cannot. The photographs that documented this particular feature were taken in May 2003. The earthwork is not isolated in this landscape; another enclosure adjoins it to the south-west, and a further one sits roughly 60 metres to the west-north-west. Enclosures of this kind are common across Ireland and often associated with early medieval settlement, though no such specific dating is recorded here. What the clustering of these features suggests is that this quiet corner of Tipperary was once a more structured and inhabited place than its present emptiness implies, its ancient geometry preserved just below the surface of an ordinary field.
