Monument record MBC45284 - medieval and/or post medieval ridge and furrow, Hillesden parish.

Almost contiguous medieval and/or post medieval ridge and furrow cultivation and furlong boundary banks, remnants of the former common open-field system, is visible on historic aerial photographs and remote sensing data as earthworks and was mapped as part of the North Buckinghamshire Aerial Investigation and Mapping project (EBC18304). Located across Hillesden parish and centred at SP 68383 29352, almost all the ridge and furrow cultivation blocks are visible as extant earthworks on aerial photographs taken in the 1940s, but aerial photographs taken in 2019 and recent remote sensing data indicate that over three quarters of the mapped blocks have since been plough-levelled due to changes to post-war agricultural regimes. The sections of linear earthwork furlong banks are part of a much more extensive system of land division boundaries that extends eastwards through Bedfordshire and beyond into Cambridgeshire. Whilst many of these features originate in the medieval period with the establishment of the common field cultivation system, some of the boundary banks may have earlier origins.They remain visible chiefly as extant, sinuous, parallel, plough-levelled earthwork sections on recent lidar remote sensing data (1- 33).
