Abstract:		 Magnitude Surveys was commissioned to assess the subsurface archaeological potential of a c.11 ha area of land at Swanwood, Henley-On-Thames, Oxfordshire. A fluxgate gradiometer survey was successfully completed across the survey area. No anomalies suggestive of significant archaeological features were identified; however, a strong and unusual anomaly was found, c.7m in diameter, of undetermined origins. The anomaly has a peculiar form, as a strong negative with a slight internal positive peak. This might be an unusual thermal structure such as a kiln, or ferrous material in a peculiar orientation in the ground. Elsewhere, the geophysical survey has detected anomalies of an agricultural origin, in the form of ploughing regimes in the north of the survey area. Natural variations have been identified across most of the survey area, relating to the unconsolidated superficial deposits. Linear and curvilinear anomalies of undetermined classification have also been identified. The impact of modern activity on the results is limited to disturbance from ferrous material in boundaries or nearby structures at the edges of the survey areas.
