An aerial photograph reveals a cropmark, the faint discolouration in vegetation or soil that betrays buried features beneath, tracing the curve of a large semi-circular enclosure roughly 100 metres east to west and 80 metres north to south. The northern boundary is not a ditch at all but the Dineen River, flowing east to west, pressed into service as a natural barrier. Whatever was enclosed here, it was substantial.

A fosse, meaning a ditch dug to define and defend a boundary, marks the curvilinear edge of the enclosure. A second enclosure, also defined by a broad fosse and with an entrance oriented to the south-east, cuts across the first. The relationship between the two is unresolved; it is genuinely unclear which came first and which was adapted to accommodate the other. Where the two enclosures intersect, a stable yard was later built, a practical reuse of the space that also obscures the very junction that would help answer the question of sequence. The site carries the kind of ambiguity that makes it more interesting rather than less, two overlapping phases of activity, possibly from different periods, neither fully legible without excavation.
