This volume contains reports on three major excavations (at Cowbit and Morton in Lincolnshire and Middleton in Norfolk) conducted as part of the Fenland Management Project. The sites are all concerned primarily with salt-making and between them they span the Iron Age to late Roman periods. The detailed work has enabled the compilation of a much needed type series for briquetage, which it is hoped will be useful in describing the material from all coastal salterns. Also contained within this volume is a re-assessment of the landscape context of the Fenland sites, an examination of the importance of salt production to the Fenland communities and recommendations for further research in this subject.
