Its existence is known only from the air, where the buried outline of a fosse, a defensive ditch dug around a settlement, appears as a cropmark, a phenomenon where crops grow differently over buried features, betraying through subtle variations in colour and height what lies beneath the soil.

The enclosure is roughly oval in shape, measuring approximately 60 metres east to west and 90 metres north to south, making it a substantial feature by any measure. It was recorded in aerial photographs taken across three separate decades: in July 1966, again in July 1975, and once more in July 1990. That it has shown up consistently across different surveys and different growing seasons suggests a well-defined buried ditch rather than an ambiguous smudge in the landscape. Enclosures of this general type in Ireland are often associated with early medieval settlement, the period roughly between the fifth and twelfth centuries, when ringforts and enclosed farmsteads were the dominant form of rural habitation. The oval outline here, rather than the more common circular form, marks it as something worth a second look, though without excavation its date and purpose remain open questions.
