It takes a particular kind of light, or rather a particular kind of summer, to bring it out. When crops are under stress from dry conditions, the buried remains of old earthworks can alter how the plants above them grow, producing faint differences in colour and height that are invisible at ground level but legible from above. That is how this enclosure makes itself known.

The site is a large circular enclosure roughly 50 metres in diameter, defined by a fosse, which is simply a ditch cut into the ground, typically used to demarcate a boundary or provide a degree of defence. Although the fosse has long since been filled or levelled by centuries of agricultural activity, its outline was captured as a cropmark on satellite imagery in August 2022 and identified by Jean-Charles Caillère. Circular enclosures of this general type are relatively common in the Irish landscape and often indicate the site of a ringfort, a form of enclosed farmstead that was widespread during the early medieval period, roughly the fifth to the twelfth centuries. Whether this particular example fits that category or belongs to an earlier or later tradition, the notes do not confirm, and the site has not been excavated.

Because the enclosure survives only as a cropmark in tillage ground, there is nothing visible at the surface for a visitor to see. Its existence is, at present, a fact known largely to satellite imagery and to those who look closely at it.
