What appears at first glance to be a simple circular earthwork is, on closer inspection, a layered system of concentric banks, ditches, and berms, arranged with a precision that feels deliberate and, given the waterlogged landscape around it, rather purposeful.

The monument is roughly circular, measuring 31 metres north to south and 27 metres east to west at its innermost enclosure. That central space is defined by a bank, a fosse (a ditch, typically cut to defend or demarcate), and an outer bank, beyond which lies a broad flat berm, a level shelf of ground about 11 metres wide, and then an outermost bank. This outermost bank is noticeably more substantial in the western quadrant, reaching a width of at least 3.5 metres, while elsewhere it has been worn down to something resembling an ordinary field boundary. A possible causewayed entrance exists in the eastern quadrant, where a gap crosses the intervening fosse; curiously, the outer bank rises in height just east of this point before terminating to the north of the causeway, a detail that suggests the entrance was deliberately framed rather than simply left open. A later field bank, running north to south, cuts across the southern section of the berm, indicating that at some point the monument was absorbed, at least partly, into an ordinary agricultural landscape.

The fields to the south are largely reclaimed and cultivated now, which throws the earthwork into sharper relief. The land rises slightly to the north and east, meaning the hillock, modest as it is, would once have offered a meaningful vantage over the marshy valley floor. The overall effect on the ground is of a monument that has been eroded and partially obscured, its western outer bank particularly worn, but whose underlying geometry remains legible if you know what you are looking at.
