SDO16354 - Bourne Farm, Piddlehinton, Dorset. Magnetometer Survey Report.

‘Detailed magnetometry was carried out by Archaeological Surveys Ltd, at the request of AC Archaeology Ltd, ahead of a proposed development of an anerobic digester plant at Bourne Farm, Piddlhinton in Dorset. Approximately 20m to the west of the survey area is the location of a scheduled round barrow, with the remains of a field system also recorded within the field and extending over the barrow. The survey data demonstrate the presence of two ring ditches relating to previously unrecorded round barrows located 25m and 75m east of the scheduled barrow. One of the ring ditches appears to be crossed by an incomplete rectilinear ditch which has a similar orientation to elements of the field system recorded beyond the survey area, and it seems likely that it is related. Both ring ditches correlate with low mounds that have not produced any magnetic response. Other linear anomalies were classified as uncertain in origin, although some may relate to agricultural activity. Magnetic debris located in a shallow depression is likely to relate to material within a former chalk pit. The site contains small zones of magnetic debris and strong discrete responses indicative of dumping and spreading of ferrous and other magnetically thermoremnant material.’
