Site F (2,040m²) was designed to explore and better define the enclosure ditch F45 found in T34 and to examine any internal features, and the Roman and post-medieval ditches running broadly east-west to the north of the enclosure. The principal discovery was three enclosures dated to the late Iron Age or early Roman period and interpreted as stock-related features; no convincing buildings were defined. There were no features predating the late Iron Age, but prehistoric activity prior to that date is indicated by the presence of hand-made prehistoric pottery and prehistoric flints in various contexts.<1>
