Monument record 0482402000 - N OF MANSFIELD FARM, IVER HEATH

Geophysical survey carried out by SUMO in May 2024 identified a small number of features of archaeological interest. In Area 5 two ring
ditches, the larger of which corresponds with a cropmark seen in earlier aerial photos, were identified along with further ditch-type anomalies and a possible rectangular ditched enclosure. Numerous weak linear, curvilinear and sub-circular trends were of uncertain origin and could be archaeological, agricultural or natural features. Possible areas of gravel extraction were also identified. In Area 1 linear anomalies interpreted as modern field boundary ditches (shown on 1937-1961 OS maps), ploughing and land drains were identified. A strongly magnetic linear anomaly running NE-SW across Area 5 is an underground service pipe [presumably the Iver-Arkley water main]. See report for detail (B5).
Pair of parallel ditches were identified in the area to the north of the field. Late Iron Age pottery was recorvered from one, Roman and Iron Age pottery from the other. Central to the field were a small group of Roman and undated features. Pottery recovered from this area was dated to the mid 3rd to the 4th centuries. A sherd of Early Saxon pottery was recovered from a Roman ditch, suggesting some form of post-Roman activity (B6).
