A geophysical survey, comprising detailed magnetometry, was conducted by Archaeological Surveys Ltd within a small area of land at Devizes, Wiltshire, ahead of a potential residential development, using a 5 channel, hand-pushed, cart-based system. A number of geophysical anomalies were located in the south eastern part of the survey area which could be associated with a formerly mapped building and its surrounding environs. Positive linear anomalies in the northern part of the site could be associated with formerly mapped boundary features, but this is not certain. A small number of positive linear and discrete responses have been located in the northern part of the site, but they lack a coherent morphology which prevents confident interpretation as former cut features. Modern magnetic debris and disturbance has also been encountered, including a number of buried services.
