Report on an earth resistivity survey, conducted of the moated medieval complex at Wragby, as part of a reseach project by the Wragby Heritage Group. Several anomalies of potential archaeological significance were detected, along with a general spread of anomalies caused by disturbance across the site. It was thought possible that some of the anomalies may represent structural remains or rubble spreads of former buildings on the raised islands, although this interpretation remains tentative.
