This volume reports on two excavations carried out by Oxford Archaeology on the outskirts of Wallingford, at Slade End Farm and Winterbrook. The two sites provide windows into the same gravel terrace landscape and together shed significant new light on the prehistory of the south Oxfordshire Thames Valley. Slade End Farm was repeatedly visited for settlement in the early Neolithic. Numerous clusters of pits were found that contained pottery, flintwork and other finds. A pair of inhumation burials was also discovered. Sparser settlement subsequently occurred at the two sites during the middle and late Neolithic and the Beaker period. Landscape organisation dramatically changed in the middle Bronze Age, when ditched field systems or enclosure complexes were laid out at both sites. A waterhole containing a log ladder was also found. Environmental evidence suggests a landscape of largely open grassland used for grazing. While no buildings were found, concentrations of finds in some enclosures suggest that they were foci for domestic activity. Several burials were also found at each site. Both sites were reoccupied for settlement during the early and middle Iron Age. Roundhouses were built, and a series of boundaries and enclosures laid out. A double pit alignment dug in the early Iron Age at Slade End Farm separated the occupied area from the lower, wetter ground to the south. One of the pits from this alignment contained an inhumation burial. A complete, decorated copper alloy bracelet that had been placed in a posthole is a rare survival. At Winterbrook, part of a settlement dating to the 11th to 12th centuries was also uncovered, providing the first good archaeological evidence for a rural community in the immediate hinterland of the medieval town of Wallingford.
