At least one possible rectangular enclosure and associated linear features are visible as positive cropmarks on aerial photographs (S1-S4), centred on TG 24136 13115.
The larger of two possible enclosures measures at least 44m by at least 58m and a smaller, second possible enclosure to the northeast measures 37m by at least 37m. The features are orientated northwest-southeast.

September 2025. Record reviewed as part of the Forestry Commission Project K
A rectangular enclosure of an unknown date (see above) is visible as a cropmark on S5 and S6. The enclosure is centred at approximately TG 2410 1312 and most likely relates to the western enclosure mapped by the earlier NMP survey (see above). Although the date of the enclosure is unknown, an Iron Age to Roman date is possible.
