It is neither a boundary marker nor a building remnant in any obvious sense. Two small apertures, each roughly sixty centimetres wide, pierce the column midway up on its eastern and south-eastern faces, suggesting intention rather than accident, though exactly what that intention was has never been firmly established.

The pillar is a solid, circular construction, approximately 1.8 metres in diameter and 2.6 metres tall as it survives, built from roughly cut rectangular limestone blocks around a rubble core. Traces of render still cling to parts of the surface, indicating that it was once finished more smoothly than it appears today. Where a section has been removed on the western side, the rubble interior is exposed. The landowner has noted that the structure was once considerably taller and may have been crowned with a conical cap, which would have given it a more obviously ornamental character. It sits roughly 250 metres to the south-south-west of Woburn House, and that proximity is the main clue to its origins. Follies, which were decorative structures built largely for visual effect rather than practical use, were a common feature of demesne landscaping among the Anglo-Irish gentry from the eighteenth century onwards. A cenotaph, a memorial structure without a burial beneath it, is the other possibility raised for this pillar, though no specific commemorative association has been documented. Whether it once anchored a designed view from the house, marked a significant point in the grounds, or served some now-forgotten memorial purpose, remains genuinely unclear.
