The monument comprises a fort dating to the prehistoric period, visible as cropmarks on oblique aerial photographs.

The monument lies within an area of arable land, on the edge of a gully which overlooks an old watercourse, at a height of around 90m OD. It forms a truncated oval on plan, and measures approximately 65m from N-S internally by 33m transversely. On three sides the site has been defended by two parallel ditches which run approximately 10m apart from each other, and there is an entrance in the east.

On the fourth side, the construction of artificial defences has been rendered unnecessary by the nature of the topography, as the site is naturally defended by a steep slope that falls away to the watercourse below. The monument comprises the remains of a defended settlement site which would probably have been occupied during the 1st millennium BC.

The area proposed for scheduling includes the visible extent of the remains described and an area around them within which related material may be expected to be found. It forms a truncated circle on plan, measuring 80m transversely and bounded on the west by a boundary fence (which is specifically excluded from the scheduling), as marked in red upon the attached map.
