An archaeological fieldwalking and metal detector survey was undertaken by Cambridge Archaeological Unit (CAU) to the north of Knight's End Road, March, Cambridgeshire. The fieldwalking and metal detector survey produced very few finds and no notable concentrations of artefacts. The artefacts present represent a 'background level' of prehistoric activity, consistent with a general presence throughout the landscape, and potential evidence of manuring for agriculture in the Roman period. The subsequent trial trenching revealed a number of modern and post-medieval agricultural features, and a number of ditches, which are potential components of a Roman field system.
