In a stretch of pastureland on the north-eastern face of a gentle rise in Milltown, County Westmeath, a standing stone was once present, substantial enough to be marked on the Ordnance Survey six-inch map of 1911. Today, no trace of it survives. What remains is the entry, the outline of an absence.

The 1911 OS map is a useful baseline for features that were already old by the time cartographers got to them. Standing stones in Ireland are typically prehistoric in origin, raised during the Neolithic or Bronze Age as markers, boundary points, or focal points for ritual activity, though their precise purposes are rarely certain. That a stone was visible and notable enough for inclusion on a map in the early twentieth century suggests it had stood for a considerable time before disappearing sometime in the century that followed, likely cleared to ease agricultural work. Ten metres to the south, an earthwork still survives, catalogued separately, and the proximity of the two features hints at a small concentration of ancient activity on this otherwise unremarkable rise of ground.
