The enclosure at Money is D-shaped, roughly 45.5 metres along its longer axis, defined by a flat-bottomed fosse, essentially a wide ditch dug as a boundary or defensive feature, that behaves oddly as it runs around the site. At the north-east it is a substantial ten metres wide; by the time it reaches the south-west, it has narrowed to five. The outer earthen bank follows a similar pattern, broad and pronounced on the eastern side, thinning to almost nothing in the west and north. A stream cuts through the fosse at the south-west corner, and a marshy area sits immediately to the west of the whole structure. None of this is typical.

What makes the site particularly curious is a detail that would only strike you once you had walked its perimeter. There is a gap two metres wide in the eastern bank, which might ordinarily suggest an entrance, but there is no causeway crossing the fosse at that point. To enter through that gap would be to step directly into the ditch. The interior itself offers no further clues; it is level and featureless, giving nothing away about what activity, if any, it was built to contain or exclude. The straight north-western side of the enclosure is obscured by a later field boundary, though the inner lip of the fosse remains visible beneath it. Whether the enclosure originally functioned as a ringfort, a stock enclosure, or something less easily categorised, the physical evidence alone does not say. Earthworks of this kind in Ireland tend to date broadly to the early medieval period, though without excavation that remains an assumption rather than a finding.
