It sits at the base of an elongated natural hollow, which is unusual in itself; most enclosures of this kind occupy elevated ground, where the view and the visibility they offered were part of the point. This one settles into the landscape rather than commanding it, and the structure itself compounds the puzzle. There is no identifiable entrance, no bank, and no trace of internal features. Whatever happened here, it left almost nothing to read.

The enclosure takes the form of a raised circular platform, roughly 44 metres in diameter and standing between two and two and a half metres high. Its summit is slightly dished, measuring around 36 metres across, and the whole thing is defined by a wide, flat-bottomed fosse, a term for the ditch or depression that typically borders an earthwork. What is particularly odd is that this fosse appears to be partly natural in origin, meaning whoever constructed the platform may have worked with the existing topography rather than cutting an entirely new boundary. The result is something genuinely ambiguous, part landform, part human intervention, and no clear evidence to settle which instinct shaped it more. Without an entrance or internal archaeology to interpret, its function remains open.
