In early September 2011 Oxford Archaeology carried out a metal detecting survey and test pit evaluation on land at Fleet Marston, Buckinghamshire. The work consisted of two phases of controlled metal detecting survey, a series of excavated shovel test pits and a further series of excavated one metre square test pits. The results showed a concentration of material around the still extant Church of St Mary, with the volume of finds decreasing significantly away from the church. The majority of dated finds from both phases of metal detecting survey came from the later Romano-British period. The test-pits contained a range of pottery dating from the Romano-British into the Post-Medieval period.
