Two trial trenches were located to investigate a square enclosure plotted from the cropmark evidence, but which was not responsive to the geophysical survey. The second trench was divided into two parts to avoid a fence line. Ditches were identified in both trenches which confirmed the presence of the enclosure together with further undefined linear features.

The cropmark enclosure was identified and excavated in both trenches . One ditch section was aligned NW-SW, with a U-shaped profile. It was filled with three deposits of
silt sand but no finds. A further section of the enclosure return was identified at the northern extent of the trench, but was not investigated.

The eastern side of the enclosure was represented by two intercutting ditches in one trench part. Excavation here identified a recut, c.1m deep ditch again with no finds. An environmental sample from intermediate fill contained carbonised grains from wheat and barley.

Two further NE-SW aligned ditches were investigated in the first trench. Both ditches had uneven V-shaped profiles up to 0.7m wide filled with deposits of the usual silty sand. Neither feature contained any artefacts.

Some of the ditches defined the square enclosure recorded from cropmark photographs. The section in one of the trench parts appears to have been redefined and enlarged at some point. The lack of recovered artefacts makes it difficult to date the enclosure, but it is likely that it is part of the wider pre-Roman Iron Age agricultural landscape recorded across this part of the Site.
