Remnant field systems and enclosures are key indicators of social change during the 2nd millennium bc – their study has considerable significance in terms of interpreting the Bronze Age in the eastern region. Despite widespread current interest in the topic, little if any evidence for Middle Bronze Age settlement and land division had been found in Norfolk prior to the investigations at Ormesby St Michael which form the focus of this paper. Here, archaeological excavations uncovered evidence for strip field systems, succeeded by a large and well dated enclosure containing at least two structures. These results are supplemented by cropmark evidence for other elements of the enclosure produced by the National Mapping Programme. When combined, the findings are of great significance since they indicate a Middle Bronze Age date for numerous comparable cropmarks recorded across the region as part of the National Mapping Programme, emphasising the crucial value of such work. It can now be suggested that the apparent dearth of Bronze Age field systems in Norfolk is not 'real', but the combined effect of limited excavation of such sites and misinterpretation of those that have been investigated.
