The excavations at Fairfield Park revealed a later Bronze Age hilltop enclosure and an extensive early Iron Age settlement. As one of the first large-scale excavations of an early Iron Age settlement in eastern England, the site makes a significant contribution to our understanding of the later prehistory of the region. In particular, the evidence sheds much light on issues of the organisation of settlement space and practices of ritual deposition. The settlement dates to around the 5th-4th centuries BC, and incorporated enclosures, roundhouses and numerous storage pits. The large artefact assemblages included high status metalwork, pottery with unique forms of decoration, and a set of 49 bone weaving tools from a single pit. Human remains and animal burials had been placed in several other pits. Good environmental evidence was also obtained.
