At roughly 78 metres east to west and 50 metres north to south, it presents as a substantial raised area, widest towards the east and narrowing at the west end. A scarp, the steep face left when ground is cut or shaped, rises to about 3.4 metres on the northern side, where it curves in a broad sweep from northwest to northeast. On the eastern side the scarp face has been cut almost vertically, before petering out to the southeast. Inside that outer edge, a raised rim of interior ground survives, from which the surface drops away and then slopes more gently towards the south. A separate terrace-like feature occupies the lower western end. What makes it difficult to read, even on the ground, is that much of the interior lies under long grass, and the uneven, pitted surface beneath suggests that quarrying at some point disturbed whatever original form the enclosure once held.

The site does not appear on the first Ordnance Survey mapping of the area, carried out in 1837 to 1838, which suggests either that it was not recognised as a significant feature at that time or that it had not yet taken its current legible form. By the 1922 edition of the OS six-inch map it is marked as a hachured penannular shape, open to the southwest, a penannular enclosure being one that forms an almost complete ring with a deliberate break or gap. The working interpretation is that a natural rise in the ground was modified and shaped to create the enclosure, though the later quarrying complicates any attempt to reconstruct the original design. A few metres to the east, a large linear bank of earth and stone runs alongside the Brusna; this turns out to be relatively modern upcast material from dredging operations on the river, not an ancient feature. More intriguing is what lies 120 metres to the northeast, across the river: a moated site, a type of medieval enclosed settlement typically surrounded by a water-filled ditch, which hints that this stretch of the Brusna was once rather more significant than its quiet, marshy present suggests.
