An early nineteenth-century Ordnance Survey map marks a circular enclosure here, roughly fifteen metres across, rendered in the hachured lines that cartographers used to indicate an earthwork of some significance. By the time the surveyors returned for the 1838 edition, it had already been quietly dropped from the record. Walk the field today and you will find nothing at all.

What the landowner describes, or described, is not quite what the map implied. Rather than a raised enclosure with a surrounding bank or wall, the feature at ground level was apparently a circular hollow, about ten metres in diameter, with steeply sloping sides and a bowl-shaped profile, more like a depression pressed into the drumlin than anything built up around it. Whether this was ever a functional enclosure in the archaeological sense, a later natural feature, or something that had already been largely levelled by the time the first surveyors passed through is not clear. What is clear is that the site sits in a cluster of more legible earthworks: a rath lies roughly 190 metres to the east, and another approximately 130 metres to the south-southeast. A rath is a roughly circular enclosure, usually dating from the early medieval period, defined by an earthen bank and ditch, and typically associated with a farmstead or settlement. Their presence nearby suggests that this part of Breaghwy saw sustained activity over a long period, even if the enclosure itself has left almost nothing behind.

The drumlin it occupies still carries the wide views southward and to the northwest that made elevated ground worth choosing in the first place. The archaeology, such as it is, may be gone, but the logic of the landscape remains legible.
