Not a fort, not a field boundary, not a practical enclosure of any kind, but a roughly circular cluster of trees, planted and arranged as a deliberate ornament in the landscape. It measured approximately 36 metres north to south and 31 metres east to west, open and unenclosed, designed to catch the eye from a distance in the way that Georgian and Victorian landowners liked their estates to feel composed, almost painterly, as though the view from the house window had been arranged like a canvas.

The feature appears on the 1838 edition of the Ordnance Survey six-inch map, one of four similar elements recorded across the same demesne. Demesne landscapes of this period often incorporated such plantings, sometimes called clumps or copses, used to break up open ground, frame vistas, or simply signal that the land was managed with aesthetic intention rather than purely agricultural purpose. That four such features were laid out at Windfield suggests a reasonably considered design scheme, even if the overall plan and the people behind it remain unrecorded here. By May 2012, aerial photography showed that the trees had been cleared away entirely, leaving only the outline of the land itself, rolling quietly on without them.
