still being farmed up to the early Roman period. The indications are that the aerial photograph does show a Bronze/Iron Age farm settlement. The site is now protected by a preservation order as an ancient monument and any future development would require complete excavation and recording.

Tracks and paths

An ancient track led from Iver to Colnbrook. Part of it followed the natural drainage ditch which ran from opposite the lane to Thorney Farm diagonally across to Old Slade Farm. The ditch now runs behind the houses in The Poynings, round the farm and under the M4, mostly in a culvert. After prolonged discussions, the path was eventually diverted to run down The Poynings and from there across to join the new bridleway bordering the motorways.
