Magnitude Surveys was commissioned to carry out a geophysical survey on a communal green adjacent to the site of the former Blacon Hall. The survey aimed to detect any archaeological remains, which would be the target for further excavation work as part of the Dig Blacon project. All of the geophysical techniques show some part or aspect of the former field boundaries, which are known through historic mapping and aerial imagery. There are some undetermined anomalies that exhibit similar geophysical properties to the former field boundaries, but have no correlation with any known features.
