Wessex Archaeology was commissioned by Kier Infrastructure, to undertake an archaeological evaluation of a 2.5 ha parcel of land located to the north of Oliver's Road, Middlezoy, Somerset, TA7 0PH, centred on NGR 337659, 134365. The evaluation comprised twenty-one trenches measuring between 20 m and 27.4 m in length, representing a 4.8% sample of the overall area, which were targeted on the results of a preceding geophysical survey. Six of the twenty-one excavated trial trenches (Trenches 1, 2, 3, 6, 7 and 11) contained archaeological features and deposits, indicating archaeological remains are present across the site, with a slight concentration in the northwest and northeast areas. The uncovered features comprised ditches, a pit and dumps of rubble/demolition material, and represent post-medieval and modern activity, though several features remain of uncertain date. The majority of the features related to the hamlet of Longacre, recorded as existing within the boundaries of the site from at least the beginning of the 17th century until the mid-20th century. There is also some evidence of earlier activity in the vicinity as indicated by small quantities of worked flint of tentative Mesolithic/Early Neolithic date, found residually in later features. Modern made ground deposits were also revealed in 18 trenches and relate to the expansion of the adjacent Wetonzoyland Airfield during the second world war.
