A magnetic survey was commissioned by Andrew Josephs Associates to prospect land off Howlett Lane, Trimley St Martin for buried structures of archaeological interest. Survey was undertaken using a GNSS-tracked non-gradiometric array of caesium vapour magnetometers on a non-magnetic platform. Survey was undertaken across two visits to accommodate harvest of an Oil Seed Rape crop that occupied much of the area. Within the data there is evidence for a medieval landscape east of the current settlement, including a former course of Church Lane. Earlier periods are represented by a sole ring ditch that in the absence of obvious settlement-related features perhaps had a funerary purpose.
