Five-sided enclosures are unusual; most prehistoric or early medieval examples tend toward the circular or oval, following the logic of a compass rather than the angles of deliberate geometry. This one measures roughly 35 metres on its longer axis and 32 metres across, its boundary formed by a stone wall that has long since grassed over, rendering it legible mainly from aerial imagery rather than from ground level.

The enclosure is part of a broader multiperiod field system on the hill, meaning the landscape around it contains evidence of human use from more than one distinct era, layers of agricultural and domestic organisation accumulated over centuries or longer. Unusually, the enclosure was not built on flat or cleared ground; it overlies half of a natural hollow in the hillside, which raises questions about whether that hollow was a practical asset, perhaps for drainage or shelter, or simply an obstacle that the builders chose to incorporate rather than avoid. A hut site lies approximately 32 metres to the north-east, suggesting that whoever used this enclosure lived close by, and that the two structures formed part of the same local complex of habitation and land management.
