The built up area of Benson is surrounded by flat farm land to the north, Benson Aerodrome to the south east (which includes housing for RAF personnel), and rising from the aerodrome on the south east side is a more hilly area of farm and woodland with some scattered houses. The Boundary in Detail Starting at the Elm Bridge Roundabout, the boundary of Benson parish goes a short distance north west along the A4074 then turns south to the river by the large hedge (boundary with Warborough), then follows the centre of the river to Crowmarsh Battle Farm (Brightwell-cum-Sotwell is on the opposite bank). It then turns south east bordering Crowmarsh Gifford, crosses the A4074 and Clack’s Lane to the Icknield Way, south to the A4130, turns east along the A4130 with Turner’s Court in Nuffield to the south. The Boundary then leaves the A4130, goes north east, north and north west around Potter’s Farm and north west over Grundon’s Gravel Pit (which is part in Benson and part in Ewelme). It then takes an irregular line up to and over the north east of the aerodrome to cross the Benson/Ewelme road (with Fyfield Manor in Benson parish and Lower End Cottages in Ewelme). The line then proceeds north along Tidmarsh Lane (Footpath 14) to the B4009, following the road west to Braze Lane, north west then south west (Kimbar’s Orchard and Port Hill House being in Berrick parish). It turns north north west crossing Bridleway l0a (Rokemarsh is in Berrick parish) goes up to the Berrick/Benson ditch and turning south west along the ditch to the Elm Brook (with Warborough on the opposite side) finally going south along the Elm Brook to the roundabout.
