It measures roughly 29 metres east to west and 24 metres north to south, and sits about a metre above the surrounding ground, with natural rock outcropping along its northern and north-eastern edges. That modest elevation, combined with the regularity of its shape, is enough to mark it out as something deliberate rather than a quirk of geology, yet its purpose remains unresolved.

The earliest cartographic record of the feature appears on the Ordnance Survey six-inch map of 1842, where it is marked as a tree ring, suggesting that at that point it supported a circular planting of trees, a common enough ornamental device on improving estates of the eighteenth and nineteenth centuries. By the time the revised six-inch map was produced in 1937, it appears instead as a hachured circular raised area, the trees presumably long gone. Its location, roughly 200 metres south-south-east of Velvetstown House and about 100 metres north of New Velvetstown House, places it squarely within what would have been a managed landscape, and the possibility that it was constructed or adapted as an estate feature is the most plausible interpretation currently on offer. Whether the platform itself is older than its ornamental use, perhaps a much earlier earthwork that was later pressed into service as a convenient site for tree planting, is a question the surviving evidence does not answer.
