Nothing of it remains above ground today, which gives the place an odd quality: a site defined almost entirely by absence.

The windmill's existence is documented in the Down Survey of 1656 to 1658, the ambitious cartographic project commissioned by the Cromwellian administration to map confiscated Irish land. Both the barony map of Forth and the parish map of Kilrane show a substantial house alongside the windmill, depicted at the eastern edge of Ballygerry, near the sea. In the looser geographic conventions of seventeenth-century mapping, Ballygerry at that time incorporated what is now the separate townland of Haysland. The mill continued to be recorded long after the Survey: both the 1839 and 1940 editions of the Ordnance Survey six-inch map mark a windmill stump in the area, suggesting the base of the structure survived into the twentieth century even as the working machinery had long since gone. A windmill stump is simply the lower masonry tower left standing after the upper works, the cap, sails, and internal mechanism, were removed or collapsed. By now, even that remnant has disappeared entirely from the landscape.
