Headland Archaeology undertook archaeological excavation of a site on land at Park Farm, Thornbury between the 25th May and 14th August 2015. Post-excavation work to date has involved the checking and ordering of the site archive, processing of environmental samples, processing of finds, the grouping of archaeological contexts and initial phasing of the site. This report summarises the work completed to date. The investigation revealed evidence for phases of earlier Romano-British land division and use, with a specific small enclosure identified. Artefacts recovered suggested settlement of the period in close proximity to the site. Medieval agriculture, in the form of remnants of ridge and furrow and field ditches was also attested. Artefacts retrieved suggested limited prehistoric activity with tentative suggestions of a heavily truncated prehistoric structure.
