It sits towards the top of a north-facing slope, buried or collapsed to the point where nothing breaks the surface at ground level. A second stump lies roughly fifty metres to the south-west. Together they are the last, barely legible traces of what was once a remarkably concentrated cluster of mills.

How concentrated becomes clear from an 1772 map by Valency, which records sixteen windmills at Townparks in St. John's parish. Valency's map is thought to have been based on an earlier source now lost, a Down Survey map, the Down Survey being the great seventeenth-century mapping project that recorded land ownership across Ireland following the Cromwellian confiscations. Sixteen windmills in a single parish suggests an almost industrial scale of grain processing, the kind of landscape detail that rarely survives in any form. By 1839, when the Ordnance Survey published its six-inch map of the area, only two stumps were marked, standing at the small green. What reduced the others to nothing, and when, is not recorded. The stumps themselves are the residue of tower mills, typically circular stone structures that could be quite substantial in height before decay, demolition, or simple neglect brought them down.
