It measures 1.35 metres in height and roughly 0.64 by 0.45 metres across, which makes it a modest but deliberate presence in the pasture. Standing stones are among the most enigmatic survivals of prehistoric Ireland, erected across a span of thousands of years for purposes that remain largely unresolved. Some were boundary markers, some may have had ritual or astronomical functions, and others seem to have been associated with burial. This one gives nothing away.

What makes the Teerelton stone particularly interesting is a small archival puzzle. When the Ordnance Survey produced its first detailed mapping of Ireland in 1842, recording six-inch-to-the-mile coverage of the entire country, this stone was not included. That omission does not mean it was absent from the landscape; standing stones were sometimes overlooked, misidentified, or simply passed by during the survey. It does mean, however, that the stone's documented history begins later than many comparable monuments, leaving its earlier story entirely open. Whether it had already been forgotten by local communities by the mid-nineteenth century, or whether it simply escaped the surveyors' attention, is impossible to say.
