A circular embanked enclosure, roughly 70 metres in external diameter, sits on top of a broad north-to-south ridge, yet at ground level, in what is now pasture, it leaves no visible trace. The only reliable record of its outline is a single edition of a map: the 1839 Ordnance Survey six-inch sheet, which captured something that the landscape itself has since quietly swallowed.

Embanked enclosures of this kind are generally understood as enclosed spaces defined by an earthen bank rather than a ditch-and-bank combination more typical of a ringfort, though their precise functions varied considerably and remain debated. What makes the Haystown example particularly interesting is its near-total disappearance from the visible record, preserved for posterity only because nineteenth-century surveyors recorded it before agricultural activity obscured it further. It does not stand alone even in its immediate surroundings: a ringfort lies approximately 35 metres to the east, suggesting that this part of the ridge was, at some point in the past, a place of some significance, with multiple enclosures occupying the same elevated ground. Whether the two features are related in date or function is not known, but their proximity on a commanding ridge is unlikely to be coincidental.
