This collection comprises magnetometer data, processed greyscale images and a CAD file containing abstraction layers for a geophysical survey of Land off Snowswick Lane, Coleshill, Oxfordshire undertaken between November 2022 and January 2023.

A geophysical survey, comprising detailed magnetometry, was carried out by Archaeological Surveys Ltd over 52ha of arable land near Coleshill, Oxfordshire. The results reveal the presence of a prehistoric settlement of probable Iron Age date consisting of trackways, irregularly shaped enclosures and at least 100 round houses covering approximately 7ha. There are a number of phases to the development of the site and evidence for round house reconstructions. Realignment of field boundary ditches to the east of the settlement may be consistent with a Romano-British phase of occupation. The trackways continue to the north, south and east beyond the limits of the settlement, with a further wide Y-shaped trackway, located 300m to the south east, associated with a curvilinear ditch and a number of enclosures to the north and south. Away from the main core of the settlement the geophysical anomalies are very weak due to poor magnetic contrast, and it is likely that there are other features with archaeological potential within the site that are not visible in the results.
