A ring ditch with an internal diameter of 11 m and a south-east facing entrance lay in the centre of the stirp, map and sample area, where it matched a prominent geophysical anomaly. A total of six sondages were dug across the feature, which revealed it to have a maximum width of 1.9 m, a maximum depth of 0.9 m and a deep bowl-shaped profile. It contained a main fill of mid–dark brown/grey silty clay fill throughout, with cobbles and stones, some heat-affected, commonly encountered.

A posthole lay within the feature’s 3.5 m-wide entrance, closer to the south-western terminal than the north-eastern.

The western portion of ring ditch appeared to have been removed by the construction of a later field boundary ditch.

The feature contained Mid–Late Iron Age pottery and animal bone, with the ceramics representing 80% of the pottery assemblage from the entire Site (by weight). The majority of this material derived from a slot, dug across the north-western part of the feature. The bulk sample from this feature contained sparse charred cereal remains (spelt wheat and barley) and seeds of grasses.

Given its steep and fairly deep (0.9 m max) profile in relation to its width, the ring ditch does not fit the criteria for an eavesdrip gully and probably represents the foundation trench for a roundhouse instead. This appears to have had a south-east facing entrance, in accordance with norms from the wider region and beyond.

The site of ring ditch was reused by a slighter feature, another ring ditch, although the relationship was not particularly convincing in light of the shallowness of the latter feature.
