In April and May 2022, an archaeological evaluation was carried out at Cotmoor Solar Farm, Halloughton, Nottinghamshire. The evaluation saw the excavation of 79 trenches.The archaeological background of the site indicated a low potential for remains other than post-medieval agricultural activity. The geophysical survey indicated a low potential for the presence of archaeological remains, with the exception of those relating to agricultural activity. These remains are likely to represent evidence of a well-established medieval open field system and later post-medieval agricultural activity. However, the limited results of the evaluation are insufficient to establish any phasing to the furrows due to the extensive modern ploughing truncating the furrow bases which were not cut into the natural substrate. The archaeological remains recorded exclusively relate to agricultural practice during the medieval/ post-medieval and modern periods. Seven ditches were identified relating to former field boundaries associated with the agricultural landscape. Two ditches replicate the alignment of furrows indicated by the geophysical survey, the remaining five respecting existing field boundaries or correlating with ditches on historic mapping from 1884. Several ditches were deliberately backfilled, likely associated with modern amalgamation of smaller fields into larger ones. Two pits were recorded associated with the agricultural activity on site. A pit in one trench was backfilled with burnt material which produced a radiocarbon date of 1043 - 1152±23 yr BP, placing the feature in the late Anglo-Saxon / medieval period. No medieval remains were previously identified within the site. A large pit was revealed in another trench, possibly a marl pit, associated with the agricultural activity.
