Headland Archaeology (UK) Ltd was commissioned by Davis Langdon on behalf of Jaynic Investments LLP to conduct an archaeological excavation on land at Hanchett End, Haverhill in Suffolk in advance of construction of the proposed Research Park. The fieldwork was undertaken between the 14th May and the 20th July 2012 in compliance with planning condition placed on the consent for the development by Suffolk County Council Archaeological Service Conservation Team (SCCAS/CT). This work followed a desk-based assessment (APS 2010) and trial trenching evaluation (Headland Archaeology 2012a). The 4.5ha excavation revealed evidence of a multiperiod landscape, with activity spanning the Late Iron Age to post-medieval periods. The primary phases comprised an Iron Age droveway and series of enclosures, succeeded by an Early to Late Roman farmstead (Fig. 61). Evidence for Anglo-Saxon occupation comprised a timber building and a burial assemblage. A post alignment at the eastern edge of the site could also be Anglo-Saxon in date. Later agricultural activity comprised a medieval quarry pit and post-medieval field boundaries, which can be identified on the 1840 tithe map. Truncation caused by this later agricultural activity had affected the majority of the archaeological remains, which were typically poorly preserved. The paucity of features indicating domestic structures might be a consequence of this truncation. Overall, the dating evidence revealed by pottery and other artefacts is mixed, prohibiting a more nuanced view of the development of the site. As such the phasing predominately relies upon stratigraphic relationships and the spatial distribution of features. This document presents the full analysis of the archaeological remains revealed during the investigations.
