Surveyed enclosure with prominent drainage channels, predating the 1825 enclosure act (Haywood 1825) and apparently in existence at the time of the 1775 Jefferys survey which depicts the current geometric road pattern. The area may be of similar date to the early surveyed enclosure described in HSY4380. The placename 'Warwick Field' suggests that the area may have been enclosed from an earlier open field. No legibility of earlier morphology as the historic boundaries between the field and surrounding former wetlands redrawn at the time of its 'improvement'.
