Tree-rings of this kind were a feature of eighteenth and nineteenth-century estate design in Ireland, planted as ornamental stands that could be seen from a distance, framing a view or signalling the presence of a cultivated property. What makes this one quietly interesting is how faithfully it has persisted: the same oval wooded feature appears on Ordnance Survey six-inch maps from both 1837 and 1914, its outline barely changed across nearly eighty years of cartographic record.

The platform itself measures roughly 55 metres on a northwest to southeast axis and just under 30 metres across, defined by a low scarp between 0.3 and 1 metre high, with traces of a bank still visible around the perimeter. The bank, about 2.5 metres wide and only 0.1 to 0.3 metres in internal height, is modest enough to be easily missed, but it marks the original boundary of the designed feature. The choice of a drumlin as the site was unlikely to have been accidental. Drumlins, the smooth elongated hills left behind by glacial movement, are a defining feature of the Roscommon and wider midland landscape, and their elevated, rounded profiles made them natural platforms for ornamental planting that could be appreciated from the surrounding lowlands.
