It was recorded, measured, and catalogued, and then, around 1984, it was gone. What had been an upright rectangular stone, just over a metre tall and oriented along a south-east to north-west axis, was removed at some point after archaeologists had visited and noted it down. The act of documentation and the act of removal seem to have occurred in uncomfortably close succession.

The stone appears on the Ordnance Survey six-inch map of 1939, though not on earlier editions, which may say less about when the stone was erected and more about the inconsistency of how such features were recorded across different mapping campaigns. Standing stones are among the most ambiguous monuments in the Irish landscape; they may mark boundaries, burial sites, or astronomical alignments, or they may simply be stones that were moved and planted upright for reasons that were never written down and are now beyond recovery. This particular example sat immediately east of an associated landscape feature, suggesting it was not entirely isolated in its original context, but part of a small local grouping of ancient remains. It measured roughly a metre in height, with a rectangular plan and dimensions of 0.45 metres by 0.63 metres, modest even by the standards of standing stones, which vary enormously in scale across Ireland.

There is, in practical terms, nothing to visit. The woodland at Ardrum remains, but the stone that once stood within it does not. What lingers is the particular melancholy of a site known only through a grid reference, a handful of measurements, and the knowledge that someone, at some point in the early 1980s, decided it was easier to remove than to leave alone.
