As a scheduled area, the site is protected to some extent by legislation;any dredging operation would have to be carefully supervised tosafeguard the banks.A geophysical survey was undertaken at the Museum's site at CoggesManor Farm (PRN 4601) to locate and identify remains of earlier buildings inthe immediate environs of the house, and to reveal any structures associatedwith the northernmost of the two moats which lie near the Windrush crossingbetween Cogges and Witney. Dr. A Aspinalland R. Walker of Bradford UniversityDepartment of Archaeological Sciences detected a number of buried anomalieswith their resistivity instruments using a two-probe array. Lowresistancereadings, characteristic of ditches, were found to the E of thehouse. High-resistance areas, indicating buried walls and possible rubbleareas were found between the house and the school: several of these linearanomalies seemed related to the present structures. Below the centre ofthe northern moat was the vague circular outline of a large banked structure,possibly a levelled motte. Other structures located indicated possiblelines of post-holes and walling. It is hoped to plan a programme of archaeologicalexcavation integrated with the long-term plans for turning thesite into a museum of agricultural history. The western side of the moat,where tree planting to replace dead elms will be necessary is one area whereexcavation will be essential.
