The enclosure measures approximately 16 metres north to south and 16.5 metres east to west, and what makes it quietly curious is the effort that evidently went into its construction: the interior has been deliberately levelled to compensate for the natural slope of the ground, and a slight terrace, around 11 metres wide, runs along the northern edge of the interior, set just 20 centimetres below the rest of the floor.

The monument is defined by a broad earthen scarp, the kind of low raised bank that marks the boundary of an enclosure, with an external flat-bottomed fosse, essentially a ditch, running around the outside from the north-east to the south-west. That fosse is best preserved along the south-east to south-west arc, becoming very shallow and hard to read further round, and disappearing entirely along the north-west to north-east stretch. Immediately to the west lies a second enclosure, and the two are divided by a notably wide north-south fosse some 6.6 metres across, which appears at some point to have been re-cut and pressed into service as a field drain, with faint traces of that drain extending outward beyond the monuments in both directions. That second enclosure also contains what may be a barrow, a burial mound, though no such feature has been identified within this one. The original entrance has not survived in any recognisable form.
