During the 1980s a large part of the Fenland of Eastern England (the country's largest former wetland) was the subject of a major programme of fieldwalking. Following publication of this work, partial excavation of 41 of the 2,500 sites discovered during the field survey, was carried out for the purpose of assessing their current condition and potential for their preservation and future management. Ranging in date from the Neolithic to the medieval period, the sites included settlements and burials, alnong with road, canals and sites engaged in specialist activities such as saltmaking. Written prior to final analysis, this report summarises the preliminary results of all 41 excavations.
