The site is a sub-rectangular enclosure, roughly 32 metres from north-northwest to south-southeast and 25 metres across, and what makes it quietly peculiar is the way the natural landscape and human construction seem to have been worked together rather than one imposed upon the other.

The northern edge is defined by a natural scarp, a low stepped drop in the ground, about 0.9 metres high and running for 19 metres, while more gradual scarps mark the eastern and western sides. A pond to the south feeds water into fosse-like channels, a fosse being a defensive or boundary ditch, that run along the western, northern, and eastern perimeters, giving the site a degree of water management that suggests some deliberate intent. The interior itself rises naturally, with the ground falling away on all sides, and a shallow linear depression running east to west cuts across its centre. Slightly off-centre toward the west, there are the remains of what may be a smaller square enclosure within the larger one. The site was identified not through ground survey but through aerial photography, which is often how these low-lying earthworks first come to light; the subtle play of shadow and crop variation that disappears at ground level becomes legible from above. The surrounding field surface is uneven from later land consolidation and drainage work, which has obscured some of the original form without erasing it entirely.
