^Aby R. Bradley, P. Chowne. R. Cleal, F. Healy and I. Kinnes ^DCurrent research in the prehistory of the East Anglian Fens, centred on the Fenland Project, attaches new significance to complementary work on the upland surrounding the basin. This volume brings together the very different results of two area excavations, at Tattershall Thorpe in Lincolnshire on the north-western edge of the Fens, and at Hunstanton in Norfolk, on the north-eastern edge. Both sites are the cumulative result of intermittent activity spread over hundreds of years, and both provide examples of apparently structured Later Neolithic pit deposits. Hunstanton fills out an already extensive picture of clearance, enclosure and land division in prehistory; and the largest structure uncovered there, a so far unparalleled trapezoid enclosure, is a reminder that whole classes of monument may yet remain unrecognised, even in relatively well-explored regions such as East Anglia.
