In the level pasture north of Kenmare Bay, near Killowen, there was once what appears to have been a standing stone, the kind of upright megalith erected across Ireland from the Bronze Age onwards, sometimes as a boundary marker, sometimes as a ritual focus, sometimes for reasons that remain genuinely unclear. It is gone now, and in its place stands a housing development. What remains is the outline of its former presence on two successive Ordnance Survey six-inch maps, the editions of 1846 and 1895, both of which mark the stone with enough confidence to suggest it was a real and visible feature of the landscape at the time of surveying.

The gap between those two map dates is telling. The stone appears on the mid-nineteenth-century survey and again on the revision half a century later, meaning it was still standing, or at least still noted, into the 1890s. At some point after that, it vanished from the ground entirely. Whether it was removed during agricultural improvement, absorbed into a field boundary, or simply toppled and buried is not recorded. Standing stones are among the more vulnerable class of monument precisely because a single upright stone, without the visual drama of a passage tomb or a ringfort's earthworks, can seem like an inconvenience rather than an antiquity to anyone who does not already know what it is.
